Many say that what happened with LUNA made the market red and difficult to recover, this is what makes us always realistic, I always follow developments and suggestions from several sites such as coinbase, coinmarketcap and so on, they suggest selling when the price drops 10%, and I followed the advice so that when the price of cryptocurrencies has dropped 10% in 3 days or less then I immediately switch to stable coins.
We can say that it did at least capitalized and started the dump. Then all the necessary things have happened for the bear market to just continue it. Everybody saw from ATH down to $29k-$31k for which bitcoin stayed there looking stably.
Whoever suggests you to sell or to buy. It's still yourself alone have to figure out on what you must do. Because you can't just rely your decision to them.
Coinbase, Binance or whoever crypto experts that you follow. You can use them a guides but not someone who just relies on them for your own finance.
