All the practical means of handling cryptocurrency involve exchanges where, sooner or later, regulatory scrutiny and the risk tolerance people have with money makes them as complicated as banks. This is the same problem people have making new programming languages and frameworks to address existing problems: sooner or later, they accumulate all the problems of the old system trying to address the limits of their simple designs.
Yes, I’m sorry you misunderstood; I was only saying it’d be easier to take pre-existing cryptocurrency, since the two exchanges required are less complicated than running an entire processor, payments network and bank. Performing the conversion to the currency is pushed off on the user and some other exchange service, and converting currency after the sale just needs to be correctly reported.
Creating an entire cryptocurrency ecosystem as an alternative to taking CCBill would not go well, I agree.
