Hashstaker is a cloud wallet, only used to stake paycoins.

If you don't know what staking is check of this video,

You put a paycoin into the a hashstaker and it sits in the wallet for a period of time.
After said period is over you may or may not receive more coins.
Isn't that like paying for the right to earn interest in this case? Not sure I understand what this will provide to the owner beside a possible speculation value for now...
