there's this thing that i forgot how it's called when you signup for it, as i did paypal is supposed to pay you 5% per year on your balance. So far I don't think i got anything, but it was less than a year
$0.66 now, which I left just in case I need to pay some dollars and a change. I try my best to transfer all funds to my bank account as fast as possible because you never know and cant trust with those online payment gateways.
