Thank you 

I would also like to know how many people have been able to change their lives thanks to BTC, for example access to private property or healthcare, it would be interesting to have access to a sociological study of the "winners and losers" of Bitcoin, that could be very interesting from my point of view.

To be honest, I was lucky enough to be able to exchange large amounts of BTC for XMR, before being able to sell this XMR for FIAT (FIAT which was used to pay for the house). In theory, since everything was P2P, the government never had a view on my main wallet.
I don't dodge my taxes tbh, I'm in a country where they are relatively low (for example less than 100 usd per year in property taxes, 10% flat tax on all incomes, 10 % on cryptos profits when >3k / year etc.). On the other hand, if I had stayed in my native country, I would probably have tried to avoid them (there it's in the 33% minimum on crypto profits and on incomes...)
