Which coin is most profitable to mine and what’s the best hardware to use for mining ?
Here is a Link for you so you can look anytime you like to figure out the answer to your question
ETH is best to mine and if you are looking for good mining hardware then I think you can bulid your own custom mining rig or can buy a ready miner which is available in the market and accordingly you can choose between the Asic and GPU miners.
According to me Alt coins are profitable to mine , and if you are looking for a good hardware then I think you should check out Promax7 .
can you provide me more information on Promax7.
I think Google can ^^
few days back I had done a reseach on Promax 7 . they have launched 2 GPU miners Promax 7.1 and Promax7.2 each giving 1830 and 3710 Mh/s respectively to mine multiple crypto currencies which i found very innovative .for more information you can check their site on the given link below .
