If the fork does not happen the price of BCU will go to zero. Buying BCU is a way for you to bet the fork WILL happen. If you bet on a horse to win and the horse does not win then you lose your bet.
Same thing here.
Only buy BCU if you think the fork will happen (or you think you can dump them for a profit on some other sucker that thinks the fork will happen).
It looks like it is not a possibility to see a BCU as yet again they failed big time when they suffered the biggest crash till date and people wont believe their stuff anymore as time and again they are proving that they are not capable to take the bitcoin to the next level.
