So what about today... Solo LUCK mining, POOL mining or ALT mine another SHA-256. What would you do?
Picked up a USB stick and a Block Erruptor CUBE as a history piece. Tried running both to verify they are functional.
Issue with the CUBE is it's GET WORK and it and the PC on my home network monoplized traffic on the router.
So what has me curious is how to scale you data traffic if mining off an ISP from home so as not to max out your limits with Mining, VoIP, Streaming TV and just Interactive Gaming?

Help recovering from old wallet.dat for an old friend.


Hey all,
I've been in the Bitcoin space since early 2012.
I have a situation that I would love to get some assistance with, I will explain the situation momentarily. Please do not message me and ask me for the wallet.dat file it's not going to happen.
TL;DR
I have an old wallet.dat file from late 2012 or early 2013 from a coin I sold to a friend. Tried to recover the coins in 2018 and failed, later found out that someone had access to the computer and could have easily stole them. Would the current Bitcoin Core be able to read an old wallet.dat file, and is there any way to easily view the balance of a 2012 wallet.dat file without having to load the entire blockchain?
In the early days of Bitcoin as many of you OG's know, the only option to securely store your coins was to use the default Bitcoin wallet in a wallet.dat file. A friend of mine was really wanted to invest in Bitcoin but didn't know how, so I sold one to him because I didn't want him to get screwed. I installed Bitcoin QT on their home laptop, had him write down the password on a piece of paper and had him put a backup of the wallet.dat file onto a USB.
Fast forward to when the price went to $20k plus, he calls me up super excited and said he wanted to sell his coin because he could use the money and I encouraged it because from my prior experience I knew the momentum was unsustainable and I had sold a few coins of my own.
Anyway, I go over to his house and we huddle around his computer. He tells me that he upgraded the hard drive in his computer and gave me his old one and I went back to my house to get an external hard drive reader. I came back, booted up his old drive and remembered that we would have to let it sync up in order to get the coins out, and on his internet that wasn't going to happen anytime soon. He gave me the hard drive and I went home and left on Bitcoin QT overnight and in the morning I was shocked to see that there were no transactions on the wallet. Quick note, he had the wallet password in a file on his documents titled "Bitcoin Wallet Password.txt". smh.
I started to panic, and I realized how bad this looked on me. I called him and told him that there were no coins on there and asked if he had his USB stick and he told me he had lost it years ago. I frantically looked through all of my old wallet files to find any transaction that could link to his address, to show that his coins were still in there. After a while I realized I had sent the coins from the now defunct btc-e.com, and had no way to check up on the coins.
I did everything in my ability to try to recover lost data from the hard drive to no avail. I asked him if anyone else has had access to his computer, and then asked him how he replaced his hard drive because I know him well enough to know he wouldn't pull apart a laptop to replace the hard drive. He told me he took it to a shop to have it replaced a few months earlier. I suspect that I'm either trying to view the wallet incorrectly or whoever replaced his hard drive snooped on his hard drive, stole the coins and replaced the wallet.dat file and generated a new one. I have to admit, I was relieved a little bit to have an explanation to coins not being there but I could imagine he thinks I may have had something to do with it. I made a few more attempts over the years whenever I was reminded of the situation to no avail.
We kind of fell out after that and haven't spoken in a while. Recently, I saw a post on his Facebook that his wife is pregnant they are having a baby, and that's why I'm here. I would love nothing more than to be able to message him and let him know that I have 11 grand waiting for him, because I'm certain the money would mean the world to him during such a stressful time.
Any help or insights would be incredibly helpful and appreciated.

Building an Ethereum Mining Rig (13 GPU) - 4th part

Third update to the guide "Building a Mining Rig for Ethereum". The absolute first guide to building a RX Vega 64 8gb 13 GPU Mining Rig.
Reading this guide to building a 13 GPU Ethereum mining rig requires adequate knowledge of building and running an Ethereum Mining Rig. We therefore recommend a previous view of our Guide to build a Mining Rig and related updates.

Let's immediately list the hardware used:

- Asus Mining Master X370 mainboard
- Core i5 Coffee Lake CPU
- 480 or 500GB SSD
- 32Gb Ram
- 13 GPU RX Vega 64 8Gb
- 3 x 1000W power supplies
- 1 1200W power supply
- 8Gb USB stick

In this guide we will obviously not explain how to mount the hardware of a Rig. The only notes we wish to underline are the following:

- the 1200W power supply must be the primary one on which to connect 4 GPUs and the video output for the monitor

- all the risers, as well as obviously the GPUs, must be powered through the 8-pole connections of the power supplies. We strongly advise against the use of 6-pole ports. Therefore, have the appropriate number of cables available for all connections. Risers can also be powered in pairs.

- the model of the video card used is the Asus Rog Strixx Gaming RX Vega 64 8Gb


The operating system is Windows 10 updated to the latest version available. The tool for creating installation media is available at the following link https://www.microsoft.com/it-it/software-download/windows10 to be able to use the USB key as a launcher for installing Windows 10 .

With the Asus Mining Master, the GPU risers can be connected directly to the motherboard via the USB cable, thus making one of the small components of the riser kits unusable.

After making all the connections on the motherboard, check that all GPUs are highlighted in green when the PC starts up. If not, move the USB cable on the motherboard one position. It may take at least 2 or 3 attempts.

Ethereum mining with 13 GPUs
Having solved this possible small inconvenience, let's proceed with the installation of the AMD Adrenaline 2020 drivers, always updated to the latest version, relating to the RX Vega Series.

If you want to proceed with more caution, the advice is to disconnect all the GPUs (remembering the locations of the USB cables) except one before installing the drivers.

The mining will be carried out on the Ethermine pool, our favorite, using the Claymore 15 software.


Once the download is complete, you will have to unzip the folder on the desktop and open the start.bat file contained in the Claymore folder using Notepad. The procedure is the usual one: delete the content and copy-paste the following command string:

start config.dll -epool eu1.ethermine.org:14444 -ewal "your ETH wallet address" -epsw x -worker "worker"
EthDcrMiner64.exe

Where EthDcrMiner64.exe is the executable, -epool indicates the pool to mine and its port, -ewal is the wallet address and -epsw is the password that we leave blank (X).

In place of "your wallet address" you will have to put your Ethererum wallet and instead of worker you will enter an identification number in case you plan to build more RIGs (such as RIG1, RIG2, etc ...).

At the following link, many other useful commands for your Rig:
https://github.com/Claymore-Dual/Claymore-Dual-Miner

Try to run mining and check that the system is stable.

In the Payouts section, after a few minutes of mining, you can decide the minimum amount of Ether to be sent to your wallet by simply entering the IP address of the RIG.

We performed the mining directly on the Ethereum address of the Exodus wallet. Coinbase is not supported.

Overclocking with OverdriveNTool
Let's proceed now with the download of OverdrivenTool at the following link: https://forums.guru3d.com/threads/overdriventool-tool-for-amd-gpus.416116/


For those unfamiliar with it, we recommend reading our software guide.

For those who do not intend to experiment or do not completely trust their software experience, at the following link you can view the settings on the parameters of the GPUs and the RAM of the GPUs - and other small tricks - to obtain the best possible performance without forcing the cards too much. video.

On our Youtube channel (subscribe numerous !!!) you will now be able to see the video relating to the start of mining and the one concerning the stabilization phase.

To better cool the Rig we have also installed fans for the extraction of heat as caution is never too much. Moreover, there is also an aesthetic gain.

Conclusions on the guide to build a 13 gpu ethereum mining rig.
Finally, we conclude this guide by reporting what everyone was waiting for (we do not say how long we had to wait before obtaining this result) the video link complhttps: //www.youtube.com/watch? V = k53XZn3zc9I & t = 61seto del Rig e del Mining .

We remain available for any advice, both on pools, on yield and on consumption.

Feel free to contact us in case you run into any problems where our guide to Building a 13 GPU Ethereum Mining Rig has not been completely helpful.

See you soon.

How i made over $150 in crypto these past 2 weeks. Here is how you can do the same.

So every week i post about how i made crypto for free.
I prefer not to pay for it so here is what has happened these 2 weeks.
Sign up for brave
Screenshot proof
I got like $90 USD in bitcoin, if you use brave you get paid for viewing ads, where as if you use chrome or firefox you HAVE to view ads and dont get paid for it.

Dolla (DLA)
This is a new crypto, you get free DLA if you sign up to their reddit, discord, twitter, faceook page and a few other social networks.
I got up to 300k DLA so far
https://imgur.com/sHT9T4e
This is a new crypto in the ICO or launch stage, they are launching on the Stallar network, according to discord chats you can cash out Q1 2021.
I would get it now while you can.. this is the rival to XRP or ripple, so .. first in best dressed.
Sign up for Dolla (DLA)

Horizen ZEN
This is the second last one for now. You get zen for playing games and referring people. This is a quality coin they are giving it away for free as well on a faucet.

Last but not least!
PI coin
use my username (patotterman) as your invitation code.
This is a free coin you can mine on your phone. It is a ponzi scheme but with no investment cost. They are currently up to 8 million users.
If it gets to 10 million, they say it will halve or get shut down. I hope it gets shut down so we can cash out.
Free for now, now value, no costs to mine, it is a share link to gain more coins link.
I think it is one of those things where its like .. I guess we will just wait and see. Based on the fact that its created by Stanford students.. Same thing with Facebook.. stated out of university. Time will tell.
---


If you are into crypto or are thinking about it, don't trust apps. websites or any third party company to hold your crypto. Get the Ledger hardware wallet backup pack
You have all of your assets on a USB stick in your own control and it comes with a visual app to show your current assets.
I use this for my crypto and it is better then any paper wallet or opensource app.

Can anyone give me a quick explanation?

Hi everybody! Beginner bitcoin miner here. I recently bought a newpac bitcoin USB stick miner just to mess around with and explore the world of bitcoin mining. I finally got it running today just off of my motherboard and it is averaging somewhere around 25 Gh/s. I'm using cudo miner btw. I have also been running my gpu, a Radeon RX 570 to mine which has been averaging around 10-12 Mh/s. When i check my stats on CudoMiner my newpac is making wayyyyy less satoshis than my GPU. Can anyone help me explain why this is happening when the newpac is averaging a lot more hash power?
Thanks in advance.

Nice hash actually carries Trojan virus

I don’t know if it’s just me but I decided I wanted to mine some bitcoin using my gpu at first I kept getting virus alert messages that I gave access btw I downloaded nice hash directly from the GitHub page they redirected me to . So then later I noticed the symptoms of the virus begin to show up. The computer started running very slowly also all my norton firewalls were off somehow I did not switch them off every time I went to switch it back on norton crashed. Then comping to the internet I don’t know if it’s Cisco Webex but it never did this before I was using my phone and it kept loading and never joined . At this point I decided to disconnect my internet from my pc. It then connected . I think bandwidth was reduced but can’t be sure it could be webex’s fault .anyone confirm if this.I booted into safe mode after and after that I could not login using my password I don’t think that is a symptom of the virus but can someone confirm this.
Update :- my pc now wasn’t booting up non of the ports were working my keyboard or mouse were not working ik cause they didn’t light up meaning no power . So I did a cmos reset didn’t work so my motherboard has the option to Re flash the bios it’s the x570 meg motherboard so I reflagged my bios and it booted up . Btw this never happened I build my pc myself tested each and every part only after I downloaded this garbage miner I started facing problems.
When u think antivirus are lying I don’t think so y other miners work perfectly fine with the antivirus only this piece of shit software doesn’t . It somehow managed to go to my bios how the f did they do that idk but I swear u literally want trouble if u download this
Edit 3:- ended up deleting windows and downloading it back from a usb stick

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

Windows
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
OSX
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

A noob is asking, is mining even possible using a USB mining device?

I'm the noob and I saw this, http://www.digitaljournal.com/p3861186
I never mined any stuff but is it ever possible to mine using a power from a USB device? If a typical GPU mining machines take so much effort to mine, how coudl this innocent "child" device could even do it?

/r/Bitcoin FAQ - Newcomers please read

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For some more great introductory videos check out Andreas Antonopoulos's YouTube playlists, he is probably the best bitcoin educator out there today. Also have to give mention to James D'Angelo's Bitcoin 101 Blackboard series. Lots of additional video resources can be found at the videos wiki page or /BitcoinTV.
Key properties of bitcoin
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.

Where can I buy bitcoins?

BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also, check out the bitcoinity exchange resources for a larger list of options for purchases.
Bank Transfer Credit / Debit card Cash
Coinbase Coinbase LocalBitcoins

Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Cashila or Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Android iOs Desktop
Mycelium BreadWallet Electrum
CoPay AirBitz Armory
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account, usually from a text message or app, making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:

So you want to stream...

Let me start this off with this is NOT a comprehensive, end-all-be-all guide to 'how to setup a livestream.' This is simply the workflow/setup I've come to use over 4 years of on and off streaming on Twitch. Hopefully it can help some of yall out that are (finally XD) joining the livestream world. *I only stream on Twitch using OBS, so this will be specific to Twitch and OBS; I have not tried YouTube, Facebook, Instagram, or any other platform or streaming software, but the basic outline is kind of there.
Hardware: 2x 1200's, Rane TTM57sl mixer with Serato Scratch Live, Samsung laptop, Behringer Xenyx 802 USB mixer, Shure SM57 mic, Pansonic GH2 or Logitech webcam (depends on if I'm using green screen or not), and then my gaming PC is my streaming PC. For speakers, I have a Yahama receiver running a 5.1 system that I use with my gaming/streaming PC. It's not the best setup for DJ'ing necessarily, as the receiver can add quite a bit of latency, but if there is any now, I barely notice it. I run the receiver in 5 channel stereo, and turn off any signal processing that I can.
Audio setup: I run 1/4" out of the booth outputs on the TTM57 into the Behringer mixer (this is for the stream audio). Then I have RCA -> 1/8" from the aux out on the TTM57 into the aux input on my receiver for my 'monitors.' I run the mic (XLR) into the Behringer mixer as well. The Behringer connects via USB to my stream PC.
Camera setup: I either use an HDMI to USB3.0 capture card with my GH2 or a Logitech USB webcam. All it takes is plugging it into the stream PC. Easy enough.
OBS setup: There are a TON of YouTube and written tutorials to setup OBS, but they generally focus on gaming and not so much DJ'ing. I won't go into too much detail, but will point out stuff more particular for DJ'ing. This is my main OBS screen. Have everything plugged in and turned on before you open OBS to make sure it picks up your USB devices (USB mixer and camera). Should go without saying, but also make sure you have your drivers installed for the devices.

The only audio I want outputting to the stream is from the Behringer mixer, so the desktop audio and camera audio are muted. Aside from the camera and mixer, all of the other sources in my source window are optional. (If you're curious as to why Winamp is in there, I can add details on that in a later post)
Output settings:
[Imgur](https://i.imgur.com/p2mIfvC.png)
Video bitrate will depend on your ISP, your upload speed, and your streaming PC hardware. I've had to drop mine down to 2500kbps from my usual 3500kbps recently. I guess with everyone at home using the interwebs, my connection seems a lot more unstable than even a month ago. I set the audio bitrate to 320kbps, but I think Twitch ends up compressing it to 192kbps for viewers. Recording settings are optional, I only recommend streaming and recording at the same time if you have a decently powerful streaming computer. Better to record just the audio in your DJ software to upload the mix later. Twitch will mute any replays with copywritten material, so I upload to Mixcloud for archiving. I run the mic through the Behringer mixer versus the mic input on my Rane mixer because I talk to chat, and it's annoying listening back to mixes with me yammering through parts. My GPU recently kicked the bucket (still works on default Windows drivers...which has caused some bottlenecks when it comes to streaming, but I can still do it) so for now I'm using software encoding, but if you have the option for hardware encoding, use it.
Video Settings
[Imgur](https://i.imgur.com/2AjjHnL.png)
Leave your base canvas at 1920x1080, but you want your output at 1280x720. I haven't really noticed a difference in the various downscale filters, but bicubic is what I use. 30fps is best for your viewers, as it's less demanding than running 60fps, but that's really up to you.
Twitch:
Twitch takes some getting used to; whether it's the website itself or the community/culture. The music community is very welcoming (especially now), and I encounter far less trolls there than in gaming channels. There's a lot of people there now trying to figure everything out, so don't feel like you're late to the party. If you want to try to make some money, you'll want to setup a donation site. Can be a simple PayPal link, Bitcoin link, or you can use something like streamelements or streamlabs. Those two extensions add other things like chatbots, commands (ie: a viewer can type !mixcloud in my chat will send a message in chat with my Mixcloud link), followesubscribedonator notifications. All of those are customizable, but I'd recommend just using the default stuff before making custom notifications and such. It can be a bit of a time sink..but then again I guess we got nothing but time right now. After you get up and going with a few streams, set your sights on reaching affilate. It's not that difficult to get, nor do you lose it if you don't keep up with the requirements to get it. You can then make custom channel emotes (again, another time sink, or there are a ton of artists out there that can make them for you) and accept subscriptions and bits.
Twitch is owned by Amazon, so if you're a Prime member, link your Amazon account and you get a free subscription you can give to one streamer per month. It doesn't auto renew, so you can change it every month, but it is a nice 'gift' to give to streamers to help support them. Dark Sith Lord Bezos does take 50% of the $5/month cost of a base subscription (whether a Prime sub or paid for), so if you really want to help a streamer, use donations. But if you already have Prime, may as well throw the free sub around to someone.
At the end of your stream, you can 'raid' another streamer. All it is is taking your viewers and dumping them into the channel of another streamer. I generally try to find other DJ's that are playing the same/similar genre that I think my viewers would stick around for; or just other DJ's I like. Then there's 'hosting.' That is when you are offline, but your channel is playing another stream. There are auto-host settings so that you don't have to manually host channels while you're offline. Between being raided (it's pretty much random and up to other streamers; don't beg) and raiding others, it's kind of the best way to get your channel out and exposed. But, don't make it about view counts or followers. Do it because you want to mix, no other reason. The music section has all of a sudden been saturated by DJ's/record labels due to the pandemic; there's a lot of people new to Twitch who don't know there's a bunch of other DJ's in the music category, so just keep going and you'll find an audience.
Other thoughts:
I love streaming on Twitch. I've done several 6+ hour streams in my time there. If you come from only playing out live, it's a big adjustment. There's no crowd energy to work off of; sometimes chat can give that to you, but it can be hard when you're just in your room by yourself. I personally find it hard to mix heavieharder stuff for more than 30-45 minutes at a time, so a lot of my mixes have been more chill and kind of downtempo as I can stay in that vibe for longer periods. I've met a lot of really awesome DJ's in my time there, and it's great seeing so many more looking for a creative outlet now that we're on global quarantine. Hopefully after some semblance of normality is restored, people will continue to livestream and the viewers keep coming back. I know this has been a giant wall of text, so apologies, but hopefully it gives someone something to go off of. Let me know if anyone has any specific questions or needs clarification on anything. Happy streaming!
