This is huge, I currently live in China where Wechat dominates messaging among everything else (I can order food, movie tickets and I pay for everything with wechat pay.) I've heard you can do much much more with wechat, although its tough for me seeing as how I can't read all the Chinese. Wechat is an all in one app created by China's unique situation. I used to live in Thailand. Line had similar (not quite as much) popularity there. I know it is also extremely popular in Korea, Japan and other places in Asia. I even remember my brother using it last year in Canada. Line is huge. Get involved early with anything crypto with line! See this story below
