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's up to you. But it's a good idea to do your own research on which coin to choose. If I were you, I would still invest in Ethereum but also in PolkaDot because the price is still low. I feel the DOT could go up again, even though I don't know when that will happen.
But again, that's just my opinion and you don't have to follow it if you have any doubts. Like my suggestion, you should look for more info about DOT because you already know how potential Ethereum is in the future.
