Honestly,, this is my first time knowing that wechat money exist and will try it out for sure.. I wont take the risk on looking for it via search engine as chance of phishing link is all around.. So Ill take time to wait for any opportunity it comes in my very face..
Nevertheless,, if it is true that it is centralized and controlled then the comparison of it to bitcoin isnt an issue no more thence alongside that its not available worldwide.. Whos the best?? Its subjective and only a users can tell..
