to ensure your funds is quite possible I think. But the essential part here is not to mix up the notions and make sure you understand how the system of insurance works.
For heaven's sake and for this forum's sake please do some research before you start posting about stuff and giving advise to others. There is currently no system that helps you insure your assets. What do people actually lose when the market drops? The amount of bitcoin they have still dont change provided they have not sold any of it. They lose the value of the asset because of market price changes. That does not necessarily mean one should look for modes to insure the values because in reality there is nothing that can do so.
Putting your funds into a company that allows you to hedge it would be another headache. Do so at your own risk.
Sure there are services that insure your crypto assets. But the risk is not USD price of the assets drops, but you loose your assets because of fraud or hackers.
