As I've written before, everyone who had the interest and the opportunity to buy cryptocurrencies has done so. And since most people's first (& only) experience with cryptos was the last year's pump & dump bubble, it's safe to assume they pretty much won't be lining up for another fleecing any time soon.
The "get rich quick" aura of cryptocurrencies is pretty tarnished at this point in time, and that's the best thing that could have happened, period. Of course, most new technologies go through a similar phase (see the .com bubble, the social networks bubble, etc.) so it's nothing out of the ordinary. A collective evolution will take care that only a few projects survive, either because they were stronger or just bloody persistent.
So, how to get out of the current cryptopocalypse? Same as always: create worth. Make that utility token actually useful. Make the thing paid for by your project's token actually worth having. Make your business sustainable. Make it valuable.
Cryptocurrencies are not a magic new thing which will disconnect you from the economic reality.
