I guess the most profiting altcoin of the moment is ethereum as it held great potential because of the ethereum 2.0 hard fork which is currently ongoing today, and also some NFTs are also gaining profits in the market today.
We don't know when 2.0 would actually come.
The devs of it keep telling that it would be delayed and it will come soon but I do agree that Ethereum is always as bullish as it is right now. But looking at it just a few years ago, it's totally low.
Like on 2018, two digits it was.
