Not quite accurate. The insurance you are talking about is for the custodial services of financial institutions. You can get custodial service for crypto with insurance too (https://custody.coinbase.com/faq). Outside of your narrowly worded agreement you don't have anything except perhaps the justice system which rarely works out in these cases. $20B were stollen in phone scams alone in the US last year, not recovered or insured, outside the insurance terms.
