Nice thread, but the list is not full as I know. There are like 10 countries where bitcoin is illegal, like Bangladesh, but the info about countries where crypto currencies are welcome seems correct. I think this information is going to be helpful for newbies.
This was the data during the G20 2018 Summit held in Argentina months ago. The countries included here are those that composed the G20 itself and a few more that were invited during the summit. The data here may now be different. For example, I cannot be sure if India remains neutral until now.
Actually, I posted this because before the G20 2018 Summit took place, news spread that one of the supposed agenda in the financial portion of the summit was said to be about crypto, and whether or not the major countries should start taking a more decisive and clearer stand on it especially since its overall value has already reached hundreds of billions in USD. This caused a little trouble or panic to some, more so because the FUDers are riding on it.
This post was my little response, a way to somehow quell the panic and trouble of those who appeared to be swayed by fake news and FUDs.
