We know algorithmic stablecoins are new and risky. UST is backed by Luna, and the foundation behind Luna bought so much Bitcoin I believe they're now amongst the top 10 holders.
If UST loses its peg against the dollar and Luna isn't enough to bring it back up, the foundation will have to sell some of its BTC to keep the peg, which applies sell pressure on BTC and brings it down along with the whole crypto market.
The trouble we are having right now is that it keeps going on and we are not recovering because Luna is still trying to get Luna better, the team and the investors are all trying their best to keep it going. They are aware that Luna will not recover but at the end of the day UST could recover in their mind, but it is not and it's 6 cents already and it's terrible.
But, the amount of money spent on trying to recover that or even trying to keep it going for a little while, instead of letting both of them to die, is a trouble. That is why I believe that we could not be really expecting them to make it back, so just let them be and the market will go up a lot.
