A couple popular mining pools are Slushpool and Viabtc. Viabtc is generally easy to find blocks more frequently and they do Bitcoin and Bitcoin Cash so switching is easy. There are many mining pools out there, so do your research and choose a pool that works best for you and your equipment. As far as how much money you can earn with different pools it’s generally about the same for the most part.
Once your miner is powered up you are ready to join a mining pool. Once you’ve joined a pool, you will want to set the pool to pay out your earnings to your Bitcoin wallet. If you want to mine a different type of coin other than Bitcoin (called Alt coins, short for alternative coins), you would locate a pool for that coin, log into your miner software and point your miner to the new pool and you will be mining a different coin.
