I sincerely wish every centralized exchange had their own SBF to burn them down. The negative impact of "investors" has been terrible for crypto. They've turned what should have been a trustless medium into a caricature of traditional banking with all of its downsides and none of the benefits. Whats the point of computing all the hashes if you end up handing your coins to some guy who pinky promises to pay them back…
Singapore doesn't tax this, you can spend crypto and transact crypto and none of that is taxable.
