I looked at the site, and it's not clear how they avoid being ripped off with charge-backs.
Any idea how they actually control/avoid fraud?
They're limiting people to like 0.046 BTC / day for $25, which is actually like $20 worth of BTC..
So basically they're counting on the fact that there's not many ppl who are going to do chargeback fraud to make 20 bucks.
