You can download any mining program for the CryptoNight PoW algo.
I use XMR-Stak myself, it's a miner that supports CPU and GPU mining (AMD + Nvidia).
+1 for XMR-Stak
i dont think there are profits when you using desktop to mining DERO coins ,gpu and asic are better.
Can you mine DERO with asic? I've been researching and trying to determine how to accumulate a sizable amount of the coins.
Two options :
1) Buy on exchange 2) Rent large hashpower for an extended period of time. Longer time is better than higher hash rate as the difficulty adjusts quickly.
I would advise against ASICs as dero (as well as most cryptonote coins) plan on changing the aglo to make ASICs useless.
