Even with BTC been more cool, etc (thousands of arguments) it is all about acceptance...
I can recharge my cellphone credits with paypal, and I'm in a country of shit.
Here you can link your paypal acc with almost every ecommerce webpage, and you can link your paypal to your CC. This makes the usage very "strong".
But I think BTC is just a step back, again, it's a matter of acceptance -- this is what makes a coin strong, like the us.dollar is much more valuable than argentine peso or any shit coin from some communist/socialist country.
BTC is very close to this point of acceptance. Paypal is a little older than BTC.
BTC is becoming much more interesting and wider than anything else.
