It offers a glimpse into the fundamental differences between individual Western social platforms and the all encompassing single app WeChat in China with over 1 billion monthly active users.

It’s like Facebook, WhatsApp, banking/credit/payments, 3rd Party services, etc. It arguably earns the title “Super App”.

What if Chinese debt trap diplomacy compelled the use of WeChat?

Is there a risk of the US Dollar global reserve currency becoming the WeChat global default platform?
