I have no clue about crytpo markets and trading but isn't the idea of using blockchain to exchange value fundamentally no different than using US Dollars? Well, except the current lack of regulation as you pointed out? I suspect the purists would argue that if/when blockchain is widely adopted and perfected for this use there would be no need for regulation. Global free trade with a single currency. A wild idea to be sure. If you separate the investing side from the "using it as a currency" side I don't think it's at all naive to compare crypto currency to the $'s you see on a screen sitting in your bank account. There's no gold out there backing our savings...only a Governments promise to pay backed by our hope that they (our GOVT) remains solvent.
