Why do you think we need Crypto Insurance when we have an easy option?
Crypto Insurance will create additional cost. With level of risk involved, no sane insurance company will charge less than 20% of the raised amount as insurance premium. Hence it would unnecessary impact project negatively. Rather than Crypto Insurance, a trusted escrow service is 100% better option. Reputed companies like Binance or Coinbase (don't bash me over this) can escrow all funds raise in ICO and release funds to team after allocation is complete.
