For me whenever I hear about the market crashing what come to my mind is the bear season and the massive dip that's gonna shake the market because I know Bitcoin, one-way or another Bitcoin is definitely going to get down probably below even 70k again when that massive dip comes in the bear season. I could remember when the market price crashed from it's previous ATH of 64k and went as low as 18k and now it have recovered and has hit another ATH of 108k. So definitely the bear season is going to come and the price of crypto and Bitcoin is gonna get splashed but recovery from this is just what is certain.
The market is more vulnerable to fud in bear market than in bull market because in bear market, people are more sensitive with bad news, fud and they are more easily panic in bear market than in bull market. It results in their actions in the market, easily panic sell in bear market but are bravely hold tight in bull market but there is another risk, if they are leveraged and hold their leveraged positions tight in a bull market, liquidation risk is high enough when the market crashes.
Bull or bear market, and whether the market crash, it's only meaninful for your portfolio if you have plans for exit before the crash or accumulation around the crash.
If you don't do anything before and during a market crash, this crash means nothing helpful for your portfolio.
