I think that someday, Bitcoin will probably overcome Paypal, because the scales in capacity and userbase all this time? We already have the ability to create our own market, and who use Bitcoin as a method of payment, so it's no surprise that both may be a tough competition for Paypal. Therefore, bitcoin must be strong.
Bitcoin has already hit Paypal on the competetion. In fact, PayPal is now a bad company, statistics show that they are losing users every day. It is very wrong to compare Bitcoin to PayPal.
