i've just made the calculations, and at the current state, bat coin is the most profitable coin to mine!
you can take one of this calculators here http://www.coinwarz.com/calculators and swap the info to bat coin's info and see for yourself
p.s
i have sent o.4bit to the mintpal votes, we need just a little bit more
Good man this is what batcoin needs, I think if we are going to pump again we wait for crypto rush to be 100% functioning again because last night was so slow
