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?
because it could go either way from buying from an exchange the same it could go either way from mining. as far as paypal goes i would never accept paypal because paypal has it in the terms/conditions that they do not honor digital currency so someone could pay with paypal dispute the charges and get their money back essentially scamming whoever isnt smart enough to not accept paypal.
