I don't think so , The DOTCOM bubble has been burst and only good ones grow, I believe cryptocurrency is a survivor but in the right way, and only good companies with innovative ideas would grow.
Yea as the guy above me said, I don't believe we will get another 2017 like bubble with altcoins, but only the good and legit companies will survive same thing happend with dotcom. I mean take a look example at ICX (icon) this company has been building during this whole bear market and continues to do so... now take a look at its price - yea wtf? Its right at the bottom like some shitcoin while on the other hand coins like "pizza" or "spaghetti" tokens bursting like crazy, this says a lot.. long term legit companies wins, always did and always will...
