Not sure what makes them think so, but there is no such a thing as absence of taxes when it comes to crypto. I am from Western Europe myself, and believe me, even your poo poo gets taxed (no joke). Just because crypto in certain countries isn't mentioned specifically by name, or that crypto isn't legal yet, it doesn't mean you don't have to pay tax. It's something a lot people think, that I definitely noticed, but that's false. Everyone is legally obliged to pay tax, especially over their gains. In some European countries you don't even need to gain or lose anything to pay tax; just holding it is enough for these countries to tax your crypto holdings every year. It's unfair, especially if your wealth get taxed regardless of your financial results, but that's the system we're in. It's rotten to the core.
