Sorry. But doesn't make sense. You also lose your money if your bank goes belly up. And even if there is government guarantee for deposits, government covers it only up to a certain amount. The rest still goes belly up. That's no different than crypto exchanges. At least, with crypto, you can have the money in your own wallet. It wouldn't get lost regardless of what happens to any crypto exchange, and you could eventually use it in any reliable exchange that exists at that point in time when you want to exchange it.
