to be honest this looks scammy, yeah you might get those small faucet deposits but it'll take a long while to withdraw anything worth the mining fee. Also I've been getting several emails offering BTG and B2X if I deposit BTC to them, even with the BTG snapshot already having taken place 5 days ago. I'd recommend people leave it there with out depositing anything in it, if it does prove legit just trying withdrawing in soe years, but don't deposit anythin!
