Some exchanges provide forms of insurance in case of violation of the wallet, what do you think about? Cobinhood for example consider repayment of the full amount
Insurance does not mean there is a guaranteed payment. Typically insurance policies come with exclusions and limits. Until the policy terms and conditions are made available for you to see, you have to assume that the insurance does NOT cover every violation of the wallet, and when it does cover a certain violation is will certainly come with some form of limitation like deductibles and maximum amount recoverable.
