I am trying to guess what will be the top 3 coins in 2 more year, say on 1st June, 2020.
Probably, BTC may not be the champion anymore but will still stand at runner-up position thanks to its historical role. ETH providing reliable platform for many valuable tokens can overthrow BTC to become the king. One of the coins with 3rd-generation blockchain like ADA or EOS will deserve the 3rd.
Anything can happen, and that's my prediction. What's yours?
I do not quite agree with you. I think that BTC will always be there and keep it first because it is a creation! The second place is ETH. When you read the white paper, I think you will recognize it. As for the third place, we cannot judge it. It seems that after two years, this kind of speculation seems to be too impulsive.
