Epic cash has been the most profitable GPU mining option especially when dual mined (time sequential, not multi-plexed.. in other words 62% of the day on ETH, 38% on EPIC).
https://epicradar.tech/miningUnfortunately, dual mining is currently just for Nvidia but we are expecting AMD support soon. I would estimate within the next few weeks. In the mean time, AMD GPUs can mine quite well using the dev-supplied native miner.
Epic Cash is also doing an "airgrab" not an airdrop by definition because of how we interact in order to particiapte. More info on the airgrab:https://bitcointalk.org/index.php?topic=5230747.160
The Epic Cash community is smart, thoughtful, and always growing. Come check it out.
telegram is the best way to interact with us but we do have discord and a discord bot connected with tg.
See you soon!
