Could be, but this survey likely suffers from selection bias.
Oh, it definitely does. There's not an easy way to get around it, unfortunately...
Actually, currency exchange is something that Bitcoin is (or, rather, will be once it is more widely accepted) really useful for. No need to take credit cards or foreign cash when travelling: just take bitcoins and exchange it for the local currency at your destination. No need to worry about theft or identity fraud or exorbitant fees or capital controls; just use Bitcoin and all the problems currently associated with currency exchange disappear. Remittance is also a prime candidate for Bitcoin use. In fact, if all Bitcoin was good for was currency exchange, that would still make it pretty darn useful in my book.
That's true. I guess I hadn't considered that. However, that's still only going to be useful for a relatively small percentage of people. Not to say it wouldn't be significant, but Bitcoin would still a long way from being adopted as a true currency.
Of course, if you're worried that it'll be too easy, then fear not. I'm sure governments are going to do everything in their power to make it as difficult as possible.
That's for sure. Bizzarely, I think that the more they clamp down on it, the more it will grow. Kind of like the Streisand effect.
