Protect against falling bitcoin and bitcoin cash prices What alternatives do I have for insuring bitcoin and bitcoin cash payments (that I'll receive in the future) against falling prices? That's against the pound or euro. Obviously that's against an x% fee.
As of 2017, the CME and CBOE offer  Bitcoin futures (but not bitcoin cash futures). AFAIK, these are the only regulated future contracts that you'll get. More ways of hedging your exposure to future bitcoin price collapses might be available in the future.
