I can see some value in crypto in avoiding oppressive governments but I rate crypto slightly above the idiotic NFT market. A fake product that doens't actually exist. If the crypto market crashes 90% or more then i might scoop some up, but I'm just not interested in a fake coin.
UST is supposed to be a US dollar 'stable coin' and equal to $1. Currently it's worth 51 cents. UST is backed by LUNA which is currently imploding. LUNA was backed by Bitcoin BTC, so they had to liquidate BTC. BTC holds the whole market up, so when BTC sells off, it takes everything with it.
it sucks because many average people are going to be hurt because they see the rich and famous and yearn for the opportunity to become the next "bitcoin billionaire" and get out of their crap existence. Of course...we all learn too late that we can't...the game is rigged against us.
A major design aspect of crypto is to make that impossible. Transactions are cryptographically signed by the crypto owner at one end (often by an external hardware device) and cannot be modified by anyone along the line.
