My advice is NOT to sell. In all honestly, I have written off my BCN as a loss.
However, many are still optimistic that the blockchain issues are genuine and when they're resolved, the price will rocket.

I do feel for the people who missed the small window of opportunity. This time yesterday, you could have cashed out at $0.24 BCN

If all the FUD is wrong, i'm certain it will exceed this price when/if the markets open again.

I'd say give it another 72hrs. Keep a close eye on Bytecoin for any announcements. If nothing after 72hrs then sell. As small as the chance may be, there is still a chance this could pay off if your patient.
