Last week, hundreds of fintech companies, from startups to tech giants, gathered at the Money 20/20 conference in Amsterdam, Netherlands. One key theme at the gathering was China’s leading role in the fintech industry. Alipay, a mobile and online payment platform, has 870 million active users, with 600 million in China and 270 million in the rest of the world.

These user numbers are a testament to how quickly Chinese consumers have leapfrogged ahead of other countries when it comes to using fintech.
