When the NASDAQ collapsed in 2001 it took almost a decade and a half to reach that peak, if you account for inflation even longer. The past couple of years it has been nothing but FANG this, robots that, deep learning, etc. the euphoria is back! So are some of the fools who lost their shirts.
Cryptocurrencies and Altcoins are even more speculative than pets.com was-at least tech companies can be highly profitable. Most of these tokens don't even have a profit mechanism and are only worth something because people buy them. I don't think the money is ever coming back to most Altcoins. Some of these scammers have moved onto the next scheme.
Follow the smart money
RE: Altcoin crash shows that cryptos are still in the hand of speculators, there are few true investors. It means altcoin BULL will have similar intensity.
