> By keeping it entirely in the crypto space, your country's tax system can't charge you for capital gains This is blatant, willful and permanently-documented tax evasion, an amusing combination of illegality and stupidity.
No, it’s not. It means you don’t pay capital gains when you’re merely exchanging one form of crypto for another. You have not realized any gains until you have converted your crypto into real assets. Converting from one form of crypto to another for the purposes of arbitrage only delays the taxes. It never eliminates them. This is really no different than selling and buying stocks in an IRA account.
You transacted into (what you believed was) a proxy for cash. That's obviously selling.
Every tax jurisdiction has rules about this because every tax jurisdiction has idiots who thought they'd found a clever workaround. (I think the first American one involved a guy in the 19th century selling property for the key to a lockbox full of cash.)
