Putting your faith into stablecoins you are putting your faith in governments and banks. Stablecoins aren't "full crypto" by any means. They are highly centralized with backing of that very currency you wanted to avod.

And good luck with your tax avoidance, that can bite you hard in the future when you need to pay them back with interest or go to jail. I am not sure where you live, but if you don't like taxes, i am guessing you have those and you live in a country that's under ever growing tighter regulations. So just hope that country you are hiding your income from has nice jails.

Also when it comes to freedom, you can have financial freedom by having enough capital to pay your taxes and live with it. Now paying taxes you'll end up literally losing your physcal freedom.
