You lose too much money. It's better to use NiceHash for mining. Create a wallet on Payyer, and the fees will be almost nonexistent. Here, it's just terrible. I used to mine on this service, but now I refuse to. After measuring the operating time on different miners, I found that this one is the weakest and cheapest. Overall, it's awful. And under no circumstances should you trust videos that are supposedly made by representatives of Kryptex.
