Exchanges will never disappear, especially in crypto. Many, many people aren't using crypto for transactions. They only want to use it to trade. They want order books to play with. That means exchanges.
I reckon it hits 2 birds with 1 stone. It creates a safer and secure environment while keeping the government regulators away from overregulating and controlling the cryptospace.
Unquestionably. But they already have the regulations. If Coincheck had been under the umbrella there's good chance their hack wouldn't have happened. Either way a unified voice is always constructive.
