Is it possible to never pay tax from BTC profit?

Let's say I bought a lot of btc some time ago. It went up significantly. Now I got enough money to live comfortably for the rest of my life. So I'm taking little from my hard wallet each week or each month. I don't need any big purchases because I can rent apartment and a car.

I have never registered anywhere that I purchased crypto. I guess the lizards could go back several years in time to see my bank transactions? Lol.
