PayPal would be a huge company to push crypto into the mainstream. A large percentage of website use it and if it accepted crypto then a lot of sites would in turn take crypto for payment. According to this article the company has filed a patent for a way to speed up crypto transactions. If you have sent bitcoin or ethereum lately you have seen the network at times can be slow (thanks cryptokitties :p). This is the next improvement that is being worked on this year. But PayPal might have its own way of speeding up transactions and it involves using secondary keys.
This is big news. Not only is PayPal looking into crypto but they are not starting there own coin. This can lead to several coins being used in their network which would bring more strength to the crypto world. I know that circle has recently got involved by buying Poloniex and we are heading closer to big companies throwing their hat into the ring.
Would you use PayPal to send crypto?
