You are right, so long as the both parties agree to it then Bitcoin can work and it can also work in both acquisition of land even if you said otherwise because Bitcoin transaction receipt doesn't require when you want to register it in the government because there are document that are even more valid than any transaction and one of them is the receipt, so how the receipt works is that after the payment has been made the owner will write it stating the amount, secondly there is what they called deed of conveyance, stating that you no longer own the land because you have transferred it to the buyer and the government will take note, so you can see that payment is not a problem to Bitcoin but the sellers.

Thats pretty wild that you have to prove the origin of your coins and go through such a strenuous process but I guess they don't want hackers to just be able to steal tons of bitcoin with it and seamlessley go on about their business with no questions asked. I'm sure there is probably a way to do it. For sure in the US this is possible and people are have been doing it for a little while although I don't exactly remember the names of the companies off the top of my head. I think its called like Holdn or something.

Yes, this is true. Actually, it depends on which country we come from, maybe if we live in El Salvador, transactions using bitcoin will not be a problem because there bitcoin can be used for transactions. However, when we live in a country that requires every citizen to use fiat as a means of transaction, then making transactions with bitcoin will be a legal problem. Although transactions with bitcoin between buyers and sellers agree, in the eyes of the law of this country it will be a legal problem, especially if buying a house or property, of course you must comply with government regulations because this also involves taxes.

So in my opinion, it is better to follow government regulations than to use bitcoin transactions but break the law. Bitcoin was indeed created as an alternative to fiat, but we must also comply with the regulations of a country because this will be wiser in using bitcoin.

I have a Binance card and im using it up like my typical debit/credit card on which of course its a great convenience since you do really just that need top up came from your Spot balance into your card balance in just few clicks. Same goes into those crypto payment options on which these are making use of crypto processors as well on which its already available in some countries, but if we do speak about p2p transactions on using up Bitcoin wallet to Bitcoin wallet then i dont believe that much that these are rampant and I do see up that majority will be making use of payment processors on which it will be just that the same on a typical fiat transactions. Here in our country there are some things that can be bought by crypto but since this will be done on p2p then i dont know if there will be that enough trust in between buyer and seller on making up such deal. If these things be done on physical manner then its just fine but if its done through online then hesitance will be there because of trust issues.
If someone do builds up a business and wanting up on having no continuous of updating on price on which they will be rather go into the path on trying to make use of payment processors on which those payments made will be directly or basing up into the current price of Bitcoin at the time that they are buying up something with it then it do automatically adjusts and everything would be done on an instant on which this is the reason on why there are still some merchants who do accepts Bitcoin or crypto payments on buying goods and other. Each country does have their own stance towards Bitcoin or crypto.

Yes, you can buy a house in Spain using bitcoins, actually. I have seen an advertisement for it on a notice board in the street, and on the internet you can also find portals about it. But I don't think there's much of a market for it. The ad I saw on the street was a tourist area with high net worth foreigners, maybe that target will buy some houses with bitcoin.

I was wondering what would happen if a European citizen buy a house with BTC in a country where it is legal to do so, for example in Spain or Switzerland, then sell the house and with the proceeds of the sale buy a house in his own country in a simpler way. I know it's a bit far-fetched  but maybe it's possible ?

If bitcoin is not yet a legal currency, using it for transactions is not a wise idea and worse if it involves large amounts of money like real estate transactions. We should not have made that transaction in the first place regardless of whether we intend to use those bitcoins for long term holding. Real estate transactions are very complicated and require government intervention, if they accidentally find out that it is an illegal transaction, we can lose everything or even be fined.

Buying bitcoin with fiat money is not too difficult even in countries that have completely banned bitcoin. So I advise everyone not to trade real estate for bitcoins regardless of our purpose if it is not considered a legal transaction.

Bitcoin is prohibited from being used openly in my country, but secretly a large number of people are using Bitcoin but the government is not saying anything. Currently, Bitcoin is used in various countries where houses, cars, and other goods are bought and sold, but in our country, Bitcoin has to be converted into P2P money through exchanges.
Since using Bitcoin in our country does not normally create pressure from the government, we can expect that Bitcoin will be legalized in the future within 2-5 years. And if it is legalized, we will be able to openly buy and sell all houses, cars, and goods through Bitcoin, we are still hoping.

Too many actions to be successful, imo. Surely, it may happen, but lots of successes should happen in a line to complete such a task.
