It would be really difficult to sell land now to a non-resident of his country. But at the same time, inside the country, I still admit such an opportunity, when the buyer and seller are sufficiently oriented in the laws of their country.
For example, the land can be issued as a gift, and the cryptocurrency can simply be transferred from the wallet to the wallet.
You are probably trying to avoid regulations. I believe it is possible in some countries, don't know about Russia. but even to a Russian it may be possible. You can announce your land in a local newspaper/website and say that you accept btc?
Your question is similar to stupidity, because it is simply impossible to sell land for cryptocurrency!
It is not stupid. Hr is trying to avoid regulations. He lives in a country where the government is very powerful and the economy is not as Free as in Europe or USA.
