A few years ago, I sold PolkaDot at its own high point after steadily buying it.
From now on, I will continue to invest in PolkaDot and Ethereum again, what do you think about the future of these two coins?
It is a good strategy but the most important aspect to consider is how you will split your funds when you invest in ETH and DOT.
ETH is the most solid out of the two but DOT is the most undervalued, the easiest way to split your capital would be to assign to each one of those coin half of your investment, but I would probably give a greater weight to ETH as it is almost a sure thing it will reach a new ATH during the next bull run, while DOT despite its potential may fail to do so.
