iPayYou is a unique Bitcoin wallet created to make Bitcoin use as simple as possible. iPayYou allows users to buy and sell Bitcoin, which can be safely stored as the private keys are encrypted on the server and are backed up. iPayYou allows users to send Bitcoin by mail and even Twitter, allowing them also to cancel transfers that are unclaimed.
iPayYou has recently introduced Amazon Direct. A system that allows users to send Bitcoin directly to Amazon to buy items.
