I've been looking into Nicehash and wanted to know if anyone had any recommendations on which coins to look at... I've been looking CryptoNightHeavy to do some Haven and Sumo mining.........
.......
I've never tried to mine both (Haven and Sumo), so I haven't an idea. And also XMR, I'm not sure that was a good idea to mine XMR with renting hashrate.
While playing with Nicehash, you should do some research to decide which coin that profitable (in-depth research). Since you will instantly lose some money as a rent cost, so, mature calculation needed.
I found an excellent post related to "Nicehash Mining Trick."
May it can help you (as your reference)
