I think when UST drop until 0.6$ can't called again with stable coin because not have meaning and function as stable coin for UST with Luna network.
USDT also fell because of the FUD news factor due to spam chain messages sent via email, I don't associate with UST even though both coins are stable but both are stable experiencing the same thing falling from the price of $1.
if tihs stable coins fud still around us , bitcoin hard to recover in near future. more over luna foundation still doing alot thing due ust pegged. if using loan to stablize ust rate , i am believe bitcoin will dumped again .
if btc and luna keeps on dumping, the stablecoin wont hold.
this is big scarry thing we will face at this moment, alot holder selling their assets to prevent more dump that caused by UST.
