This happened with all markets who gained in due time and return to same level with decline of BTC price. I think it would take much longer time than expected but by the end of the current year it will be into very strong position and price will be on good floor.
I see some people dumping their UTK as it increased more than 30%. But dont forget that the price was 8x of what it is right now in the early days. Once the project gets real time, this will be back to its former price.
No reason to sell now. Hold it and see where it will go. Lots of positive news and a good dev team.
