paypal already became an old fashoin method to pay
Old is Gold, you haven't heard that? Paypal is a very old method of payment. but still paypal is primary payment source of millions of peoples and thousands of online companies and marketplaces.It definitely is.
However bitcoin is gaining traction and i wouldn't be shocked at all if I could time travel into the future, say 10-20 years that Paypal has been completely eliminated by decentralized alternatives like bitcoin and Ethereum.
Right now people don't know about bitcoin and Ethereum yet.
It'll have a breakout year soon, maybe 2020 when block halving happens again
There is just so much in bitcoin that paypal can never have, decentralization, store of value, trustless transactions, etc.
