Freaking out here!! accidentally bought a bunch of eboost on Bittrex. Cant sell during the ICO!! Im bracing for loosing all my money

anyway of getting out of this?

short answer: NOPE.
there are no refunds on scamcoins sadly, friend :/
you can ask trex, say maybe you screwed up or something on the button press, but i doubt they do much, but no harm asking them!

IF you do get stuck with those coins, keep the community updated on how it all works out please
Good Luck!
