I was surprised by this list, I was worried that there would be no safe exchange to save crypto assets.
It should be a concern that security is important and users must get a guarantee. I like binance with their guarantee after the Hack case (SAFU).
Hopefully other exchangers will do the same thing with what Binance Exchange does by insuring their exchangers so that if something goes wrong, someone can be responsible for the funds of investors and traders.
Binance did this because of fear of loosing their legacy and had they not done this, they would have no doubt lost users and money of course. So they preferred to save their trust and now people are back on the exchange with more enthusiasm and work to make money by investing in crypto. Binance did so because they had the money and I am not sure if any other exchange out there would be able to do so.
