The scammers do tell me something. In my view Bitcoin has some real utility and 'value' precisely for the same reason that it attracts so many scammers. As long as people want some form of digital, hard to track, irreversible way to exchange things that can't be duplicated then Bitcoin will have some value. Drugs, guns, donations to political organizations, scamming, etc etc. Those are big forces with a fair amount of market value; If Bitcoin is the best way to trade in them then of course it will have value.
