Thanks for the good tip on how to exchange your UST, but I REGRET 
to inform everyone that I am unable to exchange my UST because the exchange requires a withdrawal fee of 1 UST and a minimum withdrawal amount of 100 UST. Please don't write here on this topic, if someday the exchange removes the withdrawal fee, I will inform you - https://bitcointalk.org/index.php?topic=5406561.0

That just does not make sense. Do you even know how exchanges work?
In order to exchange your UST, you need to deposit it on the exchange, so you do not have to worry about the withdrawal fee and minimum withdrawal amount.
