The only thing that's promising is Bitcoin, right now many altcoins will suffer a massive loss until 2024 gets nearer, this is how crypto performs after every massive pump or bull market, if altcoin is all you ever wanted then you need to wait, after few months your favourite coins will be much more affordable.
Well I always say 'promising' is the same as 'potential' everything has it,,, even shitcoins have promise and potential.
Bitcoin and Ethereum are the ONLY coins with utility. As in, real utility to do real things not just NFT and Defi nonsense.
If you want to play with fire,,, play on with altcoins but know that you will get hurt because altcoins are always trash coins.
