If I have Bitcoin and the real estate firms accept it as payment, I will gladly choose to pay with it. The process of changing the Bitcoin to fiat before using it to pay for the property is expensive, time consuming and sometimes risky. It will also save me the stress of going through bank procedures, which makes the transfer of huge sums difficult. In some cases, the banks are mandated to report any financial transactions that exceed a certain amount to law enforcement agencies. Volitility, legal issues or tax is not a problem to me if it is a one time payment . Since my country recognizes crypto currencies as a currency there will be no legal problem. Also, the taxes on crypto gains and transactions are not too high, so no much worries.
I think I totally agree with that because the banking situation in our country is quite similar to what you've explained, and it would even make things worse if you were converting your cryptocurrencies to fiat and receiving a large sum in your account from an unknown source. The bank will possibly freeze your account and the funds and the first thing they will ask from you is to provide proof of the funds that you've received, they will even ask for information about the sender.
Now, if you have used a P2P platform to sell your crypto to fiat, you will barely have much personal information about the person who has sent the money, so you will get in trouble because of that. That's why, if it's possible to pay directly pay with cryptocurrencies without having to go through all those implications and issues, it's a great deal.
