Whether it is a bear market or a bull market, it should be profitable. We should continuously improve our investment strategy in our investment. Of course, investing in a bear market is relatively more difficult, so we should be more cautious and don't invest too much at once. 
I seriously doubt how much you know about the market, trading and how long you have been in cryptocurrencies. Or maybe you are just posting nonsense to get your post count quota done for that day.Bullish markets are good for those who are bagholding coins for a long time and are impatient to cash it out and dump them all. Thats how they are going; buying at low and selling at high. That would not be the time to buy though.
Bearish markets are good for buying and stockpiling coins which you hope are going to make bullruns in future. Its like prep phase before the selling.
