What happened to UNI, LINK, AVAX & DOT?

I was heavily invested in these coins, until I sold my majority of them in December for profit.

I’ve been debating buying back into them, but long term predictions I’ve been studying, seem to be showing little to no upside on them in the coming years.

Are these coins dead? I used to think there was a lot of utility in them; but I guess it’s not being adopted?

Just looking for any additional information / guesses / possibilities / predictions for these coins.

I know nothing is certain, especially right now but I just kind of want to have a discussion about it, since it’s such a good time to buy in.

Cheers!
