Altcoins will be very difficult to read especially to traders and much more on margin traders. But for investors, I guess it's not that hard, especially for the top altcoins. Those who bought altcoins last year and this year will surely benefit from the incoming bull run in 2024 and 2025. I doubt there are bettors here that the whole crypto market won't be bullish in those years. It's been shown since the first halving of bitcoin and it will be the same next year.
DCA is the best technique I have seen so far because there will be huge swings before the big bull run starts.
