This is the problem - there isn't any answer to that question. And I seem to be one of the very few on here that
doesn't think the baby (and the entire bathroom) should be thrown out with the bathwater.
To attempt an answer would require more information than you should give random people on the Internet... but I'll start with:
1) What is your expected exit timeframe?
2) Are you OK with losing potentially 100% of the investment? (Not would you be happy... no one would)
3) Do you believe the value in crypto to be security, anonymity, or advanced features?
Unless you are really looking to gamble... I'd immediately forget about 99% of them and focus on either BTC or ETH and perhaps their "ideological offspring" (BCH/ETC). Almost everything else is simply a fork of or based upon those two. If you think regulation based on environmental impact is more likely... then tend more toward ETH as it's
moving to a PoS model. If you want the
relative safety provided by the largest user base and greatest number of vendors accepting it for exchange then BTC is the obvious choice. If privacy and anonymity are paramount (with the understanding that this also increases risk of regulation and ultimately supports crime to some extent) then check out Monero (XMR).
If you want or expect to quadruple your money in a few months with a significant chance of loss... then probably better to just go to a casino. The only places you're likely to find that now are shitcoins which are meme'd by a celebrity or something (ala Doge/Musk pump).
Unlike many here, I'd still say go for it if you're aware of the risks and truly support the core concepts of the chain/network/coin you're supporting - but think of it more like a donation which has a very remote chance of returning significant gains if given enough time. However, what you personally support and believe is ideologically superior to present financial systems... that I can't answer for you.
If you want a more regulated investment with far less chance of significant gains but with similarly reduced risk of loss - I would look to mining hardware providers, blockchain companies, etc. Consider
NVDA,
RIOT,
COIN,
SQ,
PYPL, etc. Also there are a few ETF's now more directly tied to specific chains, but I've not investigated them so I couldn't comment.
Sorry if that's not the answer you were looking for.
