This is the problem of the word "hodl." When the market falls common sense, sell your alts immediately. Don't be so stupid that you'll hodl that thing even though it is purely a shit coin.
Better not to buy loads of Cryptocurrencies just for the sake of buying them except you are a day trader. Only buy and hold if you believe in the tech... It's as simple as that.
By the way, if you invest with common sense you will most likely make good money in any direction the market goes.
I expect that people already know by now the importance of having money in stablecoin reserved for dips. The Reserve should be spent bit by bit on dips. You shouldn't just dump the whole thing on a single dip.
