I have traded and followed the trend, it is not 100% accurate in line with what we expect... yes, sometimes short-term trading is quite troublesome because the guess is very difficult... or maybe I am not talented enough to be a short-term trader.. idk...
Currently I don't really care about the trend, what I care about is only buying when the bullish period has gradually finished... DCA is still the best practice for me, and it is suitable for the long term... of course it only applies to coins with good liquidity and has a strong community base.
