In bear market it is a good idea to buy certain tokens because at low price if you buy coins then when the market is high in worth then you will get more of it than you buy. One more thing is that select certain good coins and make trading in some different tokens so you will be in profit because one coin goes down so there will be in little loss as you have use little money in different coins.
Nah, you haven't seen the trading discussion threads during the bear market. Plenty of people advise don't DCA or buy into the altcoins dip because if BTC went down, altcoins drop even further. Most agree you should stay at top altcoins like ETH, BNB,... and BTC. They're far better to have for you against the bear market downturn.
