I never see such service, it seems impossible. Insurance backed trading is very high risk, especially in cryptocurrency environment that has a volatile market.
Basically insurance need a platform for growing their customers money, but it's require credible platform. Suspicious platform only brings harm to the company, especially to its customers.


I found the article about the exchange https://cointelegraph.com/press-releases/introducing-bispex-a-one-stop-crypto-prediction-market-platform
