I love Antminer S19 and it's my favorite Miner because it's super powerful and also it's able to mine good amount of crypto. By the way I like to make Masternode Instead of mining. As Masternodes work on a Proof of work system.
And what coins do you mine? Masternodes work on the Proof-of-Service protocol and there is nothing similar to mining in the work of masternodes. If you are the owner of a masternode, then you are required to have the required number of coins and provide service to this node.
