somebody please tell me why someone would rent a rig for x btc when they could just buy more than they could mine from an exchange? wouldn't this be more profitable if you accepted paypal for those that down already have btc to trade with?
While I agree, Paypal is touchy as far as crypto-currency is concerned. We have had an account suspended due to selling coins, and while I believe leasing rigs is acceptable at this time, that may change at any moment.
From what I've seen, Google Wallet might be a better avenue to pursue.
