they should make a map of the countries that legalized bitcoin, I believe that 5 countries would not arrive. let's not confuse things, Most countries allow their people to use bitcoin, they have not legalized bitcoin. The bitcoin legalization process is the slowest, even though bitcoin has been around for many years. maybe it's because of political issues
The last time that I checked Bitlegal, there were a few dozen countries being given in green, which meant that Bitcoin was completely legalized in those countries. These included Japan, United States, and most of the European Union member nations. So your argument claiming that only 4-5 countries have made it fully legal is not valid. Also, during the past few months there have been encouraging signals in this field and more and more countries are looking forward to make the cryptocurrency completely legal. The death of the ICO market was a boon, as it prevented a lot of scams which would have otherwise tarnished the reputation of the market.
