The Bitmain Antminer S21 is the best Bitcoin miner in the world, or well it was supposed to be, but actually, it sucks, because I have 2 of these, and one of them broke 1 week later, I fixed it, and then another issue happened with this BTC ASIC mining rig.

The Bitmain Antminer S19 was a legendary Bitcoin miner, truly the next generation of the Bitmain Antminer S9, as the Bitmain Antminer S17 and some of the other BTC miners kind of sucked… The Antminer S21 by Bitmain has been highly anticipated, and many people including myself were quick to order these, because of the great performance of S19 miners overall.

Well right now it looks like the MicroBT whatsminer m60s is the best new BTC miner because these new Antminers have been troublesome!
