So someone signs up for the trial membership level (10TH/s), but the website min. withdrawal limit is 0.003 BTC ($21.25) and a 0.0005 BTC ($3.54) fee. Any website can show pictures of their "mining facilities", distribute $1.20 everyday to an account for seven days and then say there's your payout. To withdraw upgrade to a higher level membership! Then once you upgrade to a higher level and have enough to withdraw you lock the account. How about building some trust with users here, offer a higher tier? Prove us wrong...
