its a scam It will die within 24 hours.
If you really feel that way, I would try to claim my bitcoin cash as soon as humanly possible and then convert them all to bitcoin since you are essentially getting 1 free bitcoin for each 12-15 bitcoin that you own (based on the conversion ratio that I am seeing right now on coin market cap).
There is no downside to trading them in now if you think it will die in 24 hours, right?
