that is great news i think bitcoin will replace all kind of things except paypal off course that is a to busy paying method that is used for years now. Many people like paypal because of their secured paying method and i like that also more then bitcoins.
bitcoin will not replace paypal. When bitcoin becomes popular, the Paypal will integrate the bitcoin.
Bitcoin's market cap is already bigger then Paypal, also the mount of transactions (in volume), so paypal can integrate bitcoin, but bitcoin will be the larger one.
Same as bitcoin is the real thing when you compared it to altcoins. Sure ETH, LISK, DAO got some real good code, but everybody knows bitcoin, merchants, consumers etc. It will takes ages
before an altcoin can achieve that.
