the ranking seems very wrong to me and checking their website through the cointelegraph link you posted below, it looks to me that they are basically saying Switzerland is #1 because it has ethereum foundation in it. and as for China as the worst, that is obviously wrong. there are at least 3 countries that have banned bitcoin and other cryptocurrencies and 1 (Bangladesh if i am not mistaken) which will imprison anyone who uses them. such countries are a lot more unfriendly than China that sees bitcoin as a legal thing!!!
