Everyone is waiting for what Utrust can do in the near future. I am saddened recently that Okex will officially delist UTK out of this exchange and I do not want to see that happen during this period. Utrust is a big project and they have a real product that can be applied in our daily lives.
Okex want to delist Utrust? Why? And where you find this information?

I see that UTK have low trading volume at all exchanges (only 35k per day) and very low at Okex. But this is because price very low now and people want not sell UTK. They are holding and waiting platform

Wasn't it delisted already? I haven't checked, but delisting was scheduled to happen at 12:00 Aug 17, 2018. You can view the official announcement of OKEX at :
OKEx Implementation of Token Delisting and Hiding. You can view possible reasons here :
OKEx Token Delisting / Hiding Guideline. Most likely low volume is one of the reasons for UTK.
