There are many sites out there when I was using gpu mining. I took the easy route and used nicehash.com. However being that I bought a few antminers I will be using http://prohashing.com. Reason why is because they switch to the most profitable coin rather then nice hash where it just goes through the nice hash protocol. When you mint a coin there are several options one is to be transacted to the coin of your choice. Which blows my mind. However you can also opt in to setup your own wallets accoss the crypto's. Let's say you want your coins to be dash, that works, lets say lite coin. That works also. It all depends on where your mining efforts are and what you want to do. You can even set it up so a percentage goes to one coin or the other. The down fall the graphic interface isn't as cool as the nicehash site. Yet if nice hash has the most profitable coin you can elect it to go to your nice hash wallet. More news will come as I set up the "beasts"!
