Regulation of cryptocurrency circulation Attitude towards cryptocurrencies The first mass reaction of most countries to bitcoin was extremely negative. Practically all representatives of state authorities of countries that spoke about bitcoin equally informed the population about cryptocurrencies - they warned against using bitcoin, mentioned that it does not have a controlling body, and if something happens, nobody will return the money to citizens. Of course, these warnings were not at all aimed at the care and protection of public finances. They were announced for the formation of a negative image of cryptocurrency in the eyes of uninformed citizens.
