Saddest thing about Crypto even more than the energy cost is the human minds it consumed. I heard people saying that Crypto is what bright graduate students want to focus on and that just too bad.

If you want to finance the un-financed or create decentralized finance go into fintech, crypto is just a bad implementation of fintech... If you want to change the world go into Biotech or Energy tech.. the next thing to change humanity is probably a better battery not a better foreign exchange market...

And if you just want to get rich by taking money from fools I would recommend setting up an online casino, there are companies that sell white labeled platforms for online casinos and those extract money from poor people with 10th of the cost to the rest of humanity and takes way less effort to set up!
