Bitcoin can provide more advantages more than traditional payment processors and i believe to replace them it's only a matter of time but i used to often to use traditional payment processors such as paypal and perfectmoney but when i know bitcoin i was decide to switch it and i think if people more likely comfortable use bitcoin than other traditional payment method then eventually they will also use bitcoin such as me so there will be a chance to bitcoin to beat them someday
I dont think paypal, perfectmoney or other digital payments are traditional payment methods. while bitcoin is still as same era with them? I think the traditional payment processor is cash.
if cash I'm sure we will replace it in the future. and comparing it with bitcoin is certainly not going to be comparable, the function of bitcoin is far more than cash, it's just that bitcoin is still not too much accepted, so its use is still limited
