Every bear market leads to the death of shit coins and with the current saga combine with the bear market more will follow suit.
Actually bearish market do affect any coins in the market depending the potentiality of the coin, so many of shitcoins give off during a bearish market, but sometimes not some do give off, because of the investors who are on queue investing such particular coins, so i will agree with your suggestion and in same vain make you to understand that fews coins do survive via bearish market.
That is why bear season is important because it will eliminate any insignificant and worthless coins in the market that will just confuse the investors and potential investors in the crypto market, just think of it as a useful season to get things sorted for you so that you won't be wasting your funds in coins that doesn't have any utility. Along with the elimination of shitty worthless coins, valuable coins on the other hand will rise and remain until the the bullish season will come.
