The advantage is clearest when it is your first transaction, so not when using PayPal or Google Wallet. Because I live abroad (Rwanda) I have more hassle with credit cards than you might, specifically they are always getting flagged for fraud because I'm not where they expect. Yes, this isn't an issue if you live in the states at a permanent address.
> I bet you that it's insanely easier to get CC than bitcoin in a lot of "developing countries", and average people from developing countries, which I assume have lower than most income, should really avoid bitcoin due to the price fluctuation. In theory it's great, in practice... not so much.
Not sure why you are using quotes, but you are wrong on this one, at least in East Africa where I live. Getting a credit card is pretty annoying and expensive in Rwanda. The vast majority of people do not have bank accounts, much less credit.
I wouldn't suggest Bitcoin as a store of value, but I do think there is potential as a form of payment in these markets. IE, buying $15 of bitcoins (which yes, can be had in various ways here) to register the domain and spending it the same day. That is indeed easier than getting a credit card here.
