I think it could be actually worth buying like 5$ worth of UST at 0.0001-2.
At 0.0001 you get 50000 UST for 5 Dollar. If UST should go back to 1$ (its pretty unlikely afterall, and could take even years) you got 50k, if not its just 5$ one loses.
Update on price action:
UST broke the green suppport, it should now act as resistance.
Until there is a plan to bring down UST Supply drastically, i think this is heading to Zero.
