BCH Mining Guide with Whatsminer M3

Bitcoin Cash is a currency that derived from Bitcoin on August 1, 2017. Its total amount, algorithm, block interval, and difficulty adjustment mechanism are basically similar to Bitcoin. The main difference is the block size. The size of Bitcoin Cash is 8M while the size of Bitcoin block was 1M. After Bitcoin Cash derived from Bitcoin, Bitcoin Cash was expanded again. Bitcoin uses SHA-256 algorithm and has a supply of 21 million, and current block reward is 6.25 BTC+Package transaction fee.

Now we can use the following miners to mine Bitcoin, including Bitmain Antminer S17, S15, T17, T15..., Whatsminer M20, M10, M3..., Innosilicon T3, T2..., AvalonMiner A921, A821, A741..., Ebit E11, E9... etc. For more details of miner hashrate, power consumption, Break-even point and so on, please visit Poolin website.

Here we will take Whatsminer M3 as an example to introduce how to set up the miner and start to mine Bitcoin. 

What You Need to Know before Using Miners:

1. PSU output power is recommended to be 20% higher than the power consumption of miner;

2. The router or network switch you are using to get connected with miners shall be ones without POE;

3. Miners can only be connected to router or network switch with wired connection;

4. Recommended operation temperature: 10-35 °C;

5. Recommended operation humidity: <65%;

6. Measures shall be taken to protect miners from dust, cax or so, otherwise hashrate board may be in corrosion and heat may fail to be dissipated;

7. Google or FireFox browsers are recommended to sign in miner backend.

PREPARATION

Before setting up Bitmain Antminer L3+, you need to make sure whether everything is ok and ready.

Tools needed: PSU, PSU power cable, miner, network cable, a personal computer for operation

A: Check the Miner

1. Package inspection. After receiving a new miner, please make a package inspection first to check whether the package or the miner inside is damaged. If yes, please take photos and contact customer service of miner producer;

2. Miner inspection. Please take miner out from package and then check whether there's deformation or damage in miner, fan, cable, fan cable etc. If yes, please take photos and contact customer service of miner producer;

3. Heat sink inspection. Inspect from both the front and back fans to check whether heat sink is disconnected. If yes, please take photos and contact customer service of miner producer;

Note: as computing boards are put in card slot chassis, you may hear some sounds by shaking the miner, which is a normal phenomenon. And don't worry about it.

MINER BUTTON INTRODUCTION

MINER CABLE CONNECTION

1. Cable connection of hash board: in terms of M3-V2.0 version, it is unnecessary to connect hash board.

2. Cable connection of control board: connect pin3 cable and pin6 cable to control board.

Note: there's no difference in using which cable to connect with which interface. Just keep in mind to plug it in with right direction, namely the direction of buckle. If error operated, hash board may encounter short circuit and damage. After plug in those cables, you need to double check if the cable is loose or not fully inserted.

3. Network connection

4. Fan connection. Check whether the plug of fan cable has been fully or tightly connected. Each fan is connected to control board with one plug.

 LOCATE MINER IP

After the miner is fully equipped and set up, the first thing you need to do is locate miner IP.

Method One: get IP address from router

1) Sign in router management page (usually it's an IP address that you can find in router instruction or label) and then you can see equipments that are connected to this router.

2) Figure out the miner you are operating according to its name or the time it's connected to router and then you will know the IP address of the miner.

Method Two: Get IP through Whatsminer tool

Download Whatsminer tool: https://www.microbt.com/server/firmware.html

MINER CONFIGURATION

After getting miner IP, you can start to configure the miner. Use a computer that is connected to the same router as the miner, and type the IP address of the miner in the computer browser address bar and press "enter" to continue.

1) There will be a pop-up page that requires you to enter username and password of the miner.

Default username and password are both admin.

2) After signing in, click Miner Configuration and then General Settings and then enter the following three urls to URL respectively.

URL 1：stratum+tcp://bch.ss.poolin.me:443

URL 2：stratum+tcp://bch.ss.poolin.me:1883

URL 3：stratum+tcp://bch.ss.poolin.me:700

The miner will connect to pool 1 by default and then pool 2/pool 3 if it fails to connect to pool 1.

Worker: worker is a combination of the sub-account you've registered in Poolin.me, a dot and a miner ID that is used to name the worker. (You need to enter sub-account here, but not the wallet address you use to collect payment. You shall log into Poolin.me to set wallet address so that you can get your mining profit daily.)

Password: any password is ok 

3) Click Save&Apply to start the miner.

4) The miner will start to work after a few seconds. You can go to Miner Status page to check details and performance.

<1> Confirmation of the mining status of miner background: after miner is connected to mining pool, you could view hashrate and other data on Miner Status page.

<2>Confirmation of the mining status on Poolin dashborad: You can log in to your BCH sub-account at Poolin.me. When your miner is connected to the mining pool, you can see real-time hashrate, active miners and other data.
