Most long-term investors will do DCA and not really pay attention to the current price, because their focus is on future projections where the development of the project is more certain... before deciding to invest, they focus on the fundamental analysis of the related coin.. so even though the current price is relatively high, they will still buy for future savings, which long-term investors always think that the future has greater potential.
So, this is still a good time to buy coins with good fundamentals, like BTC and ETH... but for short-term trading purposes, it's a little harder to know.
