Crypto isn't bullshit well most of it is but the utility is still used by millions of people around the world, specifically USDT and USDC which they proven a good way to move your assets without too much regulations.
A Money Market Fund gives you interest if you are able to access it.
This is kind of a pattern:
1. There is some regulation that is inefficient ( e.g. taxi medallions, KYC, copyright protection ...)
2. New technology comes about which allows startups to claim that they have invented a new area that should be regulated differently
3. Turns out (2) is not true and new technology can easily be mapped to existing regulation but it would look bad for the regulator to take away the punchbowl
4. There is some down-turn (bubble pops) and the regulator takes away the punchbowl OR investors have accumulated so much money/power that they corrupt the government to have new rules for their businesses
