Of course, to the extent that it IS "difficult and expensive to buy bitcoins," the problem is entirely on the side of the legacy payment systems. Thus, it would be more accurate to say "it's difficult and expensive to transact with fiat." And that's precisely why Bitcoin will be successful. I remember, when I first got into Bitcoin, having to figure out how to send an international wire transaction. It was kind of a pain. It cost me 45 bucks to send a thousand. And it was like three days before the money was credited to my newly-created Mt. Gox account. After purchasing my bitcoins, it took me about ten seconds to transfer them to my personal wallet. At a cost of less than a penny. Those contrasting experiences really drove it home for me. It's like the Berlin wall. The barriers aren't really there to keep you out of Bitcoinland. They're really to keep you locked in Fiatville. And like the Berlin wall, they're ultimately doomed to fail.
You arent being realistic at all. I dont hate bitcoin and dong care for it either so im not biased whatsoever. Bitcoin is difficult to get compared to fiat money. You have no guarantee that you will even get the coins after you purchase them and there is nothing you can do about it if someone decides to rip you off. Im not talking about trasnfering my coins to a wallet. Thats simple and means nothing becausey ou already have the coins. So pelase tell me what happens whne you purchase coins and dont receive them? Do just go complain on a forum? Pretty much all you can do.
