I disagree with you there. Crypto-Currency has similar utility to currency, like standard money ($), not only that it has many advantages of being out of the control by a money-printing government. The issue is that crypto has mad speculation and has not settled on a stable valuation and the people jumping into crypto, don't see it as similar to the Forex market (which is wildly volatile, but has a baseline for evaluation). They view crypto, similar to gold or silver, which maintains a stable evaluation over the long term, instead of something that is wild if not growing like crazy.

Crypto as a market is going to need to have the bubble burst as bigger players begin to move in. Only then, do I think that crypto-currency goes from a casino to a legitimate technological innovation. Once the bigger players adopt it, more people will desire to accept it and the worth of crypto goes up. What does need to happen though, is that some of the currencies need to die. There is too many that have no basis and no usage.
