In some countries, you can buy or rent a house in bitcoins. But what are the tax and administrative implications?
In France, you can, in theory, buy with BTC, but you have to pay taxes and notary fees in euros.
Since you also have to pay capital gains tax and (unless I'm mistaken) prove the origin of the bitcoins. Justifying the origin of funds when you won cryptos with games or airdrops and then sold them to buy btc 15 years ago is almost certainly impossible.
In the end, it doesn't seem so attractive to buy in btc in France because of the administrative and tax complications, in addition to the 30% capital gains tax (unless I'm mistaken).
How is it in your country ?
In my country, payments using Bitcoin are prohibited (because it is regulated by the state, only Rupiah is permitted), but for P2P, it is usually not a problem as long as the buyer and seller have agreed with each other and promised not to harm one party (reporting it to the authorities).
I also plan that if I want to buy a car or a house, I will ask the seller whether they accept payment with Bitcoin because making transactions with Bitcoin is easy, simple and transparent.
