In my opinion, the best are WhatToMine (I like their telegram bot) and nicehash calculators
WTM is one of the worst lol. should be WHAT TO SELL not WHAT TO MINE. chasing the current most profitable is not the most profitable way to mine.
So.... what is the most profitable way to mine?
lol why would I disclose that? To ruin my own profits? This is crypto...once a niche is exposed its done and you have to find something else to exploit.
