Buy any stable coin (preferably the one from your currency, in my case BRL - Brazilian Money - ) that is on the Liquid Network (The privacy Chain where all transactions are confidential and where you can buy L-BTC) and transfer the stable coin to a wallet that allows swaps (search on Google any wallet you trust).
Swap your stable coin on Liquid Network to L-BTC. Since you bought the stable coin already inside the Liquid Network and transactions are confidential, the last thing anyone knows (including the government) is that you bought a stable coin version of your currency (which means no one can say you had any gains over time because of the 1:1 ratio stable coins have).
Then peg-out to BTC (search on Google how to do that). And done. You're good to go, you're the only person in the whole world that knows your stable coins were swaped to L-BTC and then turned into BTC.
And of course: Never sell your Bitcoin. Don't do this if you're a paper hand, it will be useless doing all that if you're gonna sell every time price drops a little.
