This is very complicated tbh.
In my opinion, Alt coins have some of the best technology and potential of all cryptos. When comparing to some of the OGs, it is clear to see that alt coins are more realistic for real world adaptation.
When choosing Alt coins, I choose an ecosystem with a strong community, good specs and realistic use cases and utility.
My current favourite alt coin is Vite. Instant transactions, feeless, gassless, low market cap, 100% decentralised and a strong and vibrant community. I believe this crypto could be a serious contender for real world adaptation and believe it could become widely adapted.
But always DYOR
