As it turned out, governments still have the ability to partially control bitcoin during transactions, given that the transaction log is publicly available. By doing various operations with bitcoin, we give the government the opportunity to track its amount, to be able to analyze who and whom the bitcoins are transferring, not knowing for sure the actual buyer and seller. However, if such information is systematized, especially if governments of different countries interact in this matter, it is quite possible to identify participants in transactions. It is impossible to just get any information about bitcoins that are in real estate in digital wallets.
