Not much... to me BTC is now just something waiting to be beaten by another coin. It was a concept and now we are looking for something new and more pratical
You have to accept if not now then very sooner then uᴉoɔʇᴉq is now a normal currency for online use and it will be the only established crypto currency all over the world, no any other coin.
Yeah and uᴉoɔʇᴉq will be more popular in future and we will see majority of sites accepting uᴉoɔʇᴉq as a mode of payment and it will be used more in compare to Paypal.
In the other side yes it will be more popular in the future and more merchants will accept uᴉoɔʇᴉq as mode of payment but unfortunately I don't see it will be used more compare to Paypal. uᴉoɔʇᴉq will just be added by the merchants as mode of payment. Paypal can touch those places with zero online connection thru banks.
And in general, I don't see any good reason why you people wants uᴉoɔʇᴉq dominate Paypal. It's not a competition. It's still more interesting if we have "many options" rather than sticking into one.
