First, referral links are in poor taste. Second, that place is a scam even though I'm in it. BTC will continue to rise because of math (and USDs being printed madly), so if they returned the $12,430 I had invested (from 4.92+ BTC), I could only purchase 2.93 BTC or so today -- a 40% loss on the capital! And I'm not even two months into the four-month period they will hold it, either.
Their model now makes a lot more sense to me, and I'm less concerned that they'll just shut down and run. That becomes more likely if the price of BTC starts to fall...
