New to Cryptos, can you advise if these Altcoins are a good bug?

I'm new to Crypto, but as I understood, after each BTC bull run, an alto coil bull run is followed, so I don't want to miss that train.

So far, based on some little research, the best coins to DCA in are XRP, Algorand, MATIC, DOT, INJ and JUP.

Of the above, INJ and JUP are probably the most promising. INJ and SOL have the same investors.

XRP has been flat for like 6 years now I guess.

Are the above good options? Can anyone recommend something?

Or maybe I should just start DCAing into ETH and BTC and SOL?
