I think bitcoin and ethereum.
you can try nicehash and get bitcoin directly
and with that bitcoin you can trade ethereum if you like
I already try with nicehash before move to aeon, they raise diff like hell, make my cpu slow to submit hashrate. I already Try with XMR, but take 1 month to get minimum payment from pool. Now I still mine with Aeon at least i still can get 1 coin/day.
every time i test with other coin i can't get profit per day from Aeon, coz i only have 1 rig.
just wondering if some one have same spec like me, maybe can share to me what coin your mine and how profit you get
thanks all.
