Insurance coverage is not important in crypto currency. It just add to the expenses to the investors, further, how could a insurance company pays crypto holders in something happen in the exchange? We are decentralized and we move in our own risk.
I won't be needing to pay extra money for insurance since I didn't leave my coins on trading sites so it doesn't worry me.
However, I got what OP pointed out since centralized trading sites are subject to hacking so regardless in amount of trader's coins it will be covered by the insurance company but I guess it isn't easy as what it seems.
Wont really be that easy for sure where you do integrate centralized exchangers with insurances.For some they might consider or accept to pay up insurance but most people wont really tend to pay up extra fee.
Same as yours I don't really care or doesn't really matter at all since I don't store up huge amounts of tokens on exchangers either DEX or centralized ones. Anything can be hacked and this thing you should always put up on your mind.
