I really do hope BTC will rise one day and replace PayPal. Atleast I don't have much trust on PayPal to do p2p transactions, and the fees are too big. Unfortunately I do not think that the cryptocurrency that will eventually replace PayPal will be bitcoin. Bitcoin is good for now as a form of investment and currency for the 20 million users or so. I think bitcoins fees will go up and code will need to be changed for it to replace PayPal.
However I think some new cryptocurrencies such as Ethereum (maybe?) have a chance in taking over, since they can improve the code and bring new features to new coins. In my opinion the smartcontract system which Ethereum and some other new coins use is going to be the future, rather than bitcoin. This is because bitcoin cannot handle the same amount of transactions PayPal does right now. Also fees would go through the roof if bitcoin would replace paypal.
Thats just my 2 cents though, who knows what will happen
