I just started mining Grin in grinmint.com (Win10, AMD). I've created account in BitForex, as this seemed like the most straight-forward way to get a wallet address where I can send the mined coins (when confirmed etc).
Can somebody who has already went through that explain the process - once there are mined coins in GrinMint, how to get them in BitForex with min.risk?

Another question - I saw some topics for Bminer being the fastest miner. I have AMD cards, so it doesn't work with them, right?

RX 580, 8GB gives me ~ 1,5 gps - is that OK, good or bad?
