It is completely reasonable.
Bitcoin Only - It is easier to accept BTC, and they need to move money fast to pay suppliers
Oh, of course. And these suppliers take Bitcoin, eh? Think about that for a minute.
I've never actually withdrawn from Gox, but it doesn't seem like selling on Gox and withdrawing funds would land in their bank account faster than an international wire. Maybe I'm wrong on that. [/list][/list]
It's quite funny, ironically so, that a purchase of this kind in the very currency we're interested in MAKING with that product is actually quite scary when it comes down to it. Bitcoin is a seller's currency (no chargebacks). No way for a buyer to revoke their funds should things not turn out as promised or expected.
Some people go on about 'I'd just take them to court!' .. good luck with working out a problem via the courts with a seller in another country when the medium of exchange was bitcoin. You'd probably get a 'lol, wut?' response from the court system.
Until recognized internationally as a legal means of currency exchange and a way to prove receipt (blockchain traces will make most people's eyes glaze over) then there will always be this fear of Bitcoin purchases 'going bad'.
