I have a collateral (100 UST), but no one wants to take it
You're a liar and cheater, and this has become obvious now that you're looking to scam some one. You keep saying you have collateral, and trying to make is sound like your collateral is worth $100, but it's actually worth less than $1.
What collateral is valid? Is 100 US Terra ok?
US Terra is a worthless shitcoin, and all your attempts to make it sound like you have collateral just earned you a red-tag. Good job.
