Firstly, the profitability of icos is reducing by the day. So whatever money you spend on your insurance for ico investment will be of no use, either you'll end up getting a loss which is more probable to happen or cut your expenses with your income at the same price. Insurance is only helpful only when the investment amount is very high and the amount f risk is very high and there is a possibility of your investment to be ruined. Otherwise insurance ends up giving you a loss only.
