I think ,that PayPal will eventually adopt Bitcoin as a deposit method, first.Bitcoin isn't a legal entity, it can't be acquired by design. They could buy an individual exchange or start their own, or even corner the market giving them effective control, but this is unlikely. Bitcoins are currently too volatile to be a unit of exchange, and exchanging money is PayPal's business.Right now PayPal is free of competition, and they like it.
