Why is UST(ustc ) pumping⁉️🤔

I am failing to understand why UST has been pumping lately it is over 40% up today, as far as I understand UST is broken and so is Luna classic. I can't seem to find any news which would support this pump. Imagine what would happen if Terra Lab were to make a proposal to fix UST and Lunac,🤔.
I guess one can always make money trading even the broken Cryptos like UST, I won't touch it at this point.
