Absolutely not, not all of the altcoins can be survived.
If you just put your money into any alts i think is a bad idea.
If we look recently there so many big coins fall, like FTX and LUNA.
So pick your alts wisely.
The most important thing is that during the fall of the market not all the coins will be able to survive. During the fall of the market the price for coins is cheap but if the coin is not necessary to everybody it means that it will be cheap forever because nobody will use such kind of coin. You may lose all your money if you will not check the information about the coin and will invest in all the cheap coins.
