Bitcoin is not competing with Paypal or Visa its competing with the US dollar. So in a sense the relationship between Bitcoin and Paypal is like the Trojan horse and Troy. If we get bitcoin inside paypal, then that will be a big blow to the US dollar.
I quite agree with blacksmithtm,
bitcoin is not competing with paypal,google pay..ecc but, with dollar,euro ..ecc other currency.
☞Although, this may affect mr PP indirectly just like what is happening now in the payment processing industry. people now see bitcoin as an alternative means of payment.
Thanks
