Paypal (payment processor) and bitcoin (digital currency) who will stay longer on internet?
Also welcome to time travellers for answer.
Bitcoin will stay longer.
PayPal is only about one company. It can disappear if this single company goes away.
Bitcoin is for all people. It won't disappear no matter how many large companies goes away.
It is doubtful to say that ordinary people bitcoin will bring what is good. And paypal is not very noticeable here. Because it is possible to analyze the surveys that will tell how many people use the Internet. And then it will be clear who is all you need.
