I don't take this to be totally true, if the crypto in question is Bitcoin, then it could be correct as Bitcoin is a long term project that's sustainable and has an actual use case, thus it could undergo correction periods and plunges, but it would eventually rise back up again, that's cause the demand will continue to rise and grow, with the influx of institutional investors, prominent individuals and the rest, Bitcoin is surely going to be around for the long term.
The sole reason i am expecting a correction which can be a big one is simply because of the presence of huge institutional investors. They started accumulating the coins knowing about halving for over an year and it is impossible to predict when they will be booking their profit and considering they are having billions worth of
BTCitcoin, it could have an impact on the market once they start booking their profit.
But having said that, I can't think the same of "every crypto", there are many pump and dump coins, lottery coins, useless/scam coins, etc, many of them are going to pump and then dump and never rise again, some others will just be pumped to scam people, and afterwards they'll dump forever, that's the situation with crypto, I believe only Bitcoin and a few other coins (like ethereum) can be trusted not to just dump outrightly.
During the last correction, the price of ETH dumped from above $1000 to below $100. So expect something similar.
