Crypto can't survive without a bear market, if not everything will remain at one spot and no reason to invest anymore what is the best strategy to prepare for a bear market and at the same time keep making a profit from the present market condition.
It's the bear market that makes the price fall. A heavy bear will market the coin die and not survive but if there will be no bear, all is going to be happy because the price will rise at most times. It makes the coin live longer but this was not possible. Bears are always here in this market and they are the opposite of the bull.
If there are no bears, there is still a normal decrease that will happen because cryptos are volatile, so it's still possible for someone to invest at lows and earn something when the price recovers. Those coin that remains on one spot are only the stable coins but even in stable coins, it's also possible to earn if you stake them.
