I tried to make a thread for you guys to connect the dots earlier, but you all simply have no clue so allow me to elaborate, pic related.
WeChat Pay is used by over a billion people (just passed 1 billion the other day), mostly in China. The use is so widespread to the point where even small vendors in rural parts of the country accept WeChat Pay. All it is a simple QR code that people can scan to send or receive payments. It's an application for your phone, and easily integrated into other POS services.
I have lived in China for 2 years, and after about 2 weeks in I never carried a wallet. Most people don't. Physical cash is not even a thing here anymore, save for some $0.20 coins used for the subway.
How does this relate to NANO? This is exactly what NANO's use case is - instant, feeless, easy-to-use transactions. NANO's mobile wallet will release in likely a week, along with the desktop wallet, and they will have QR codes as a payment method.
Why would people use NANO and not WeChat Pay? Well, I can't speak for those in China, as likely most will stick with WeChat Pay. That said, the rest of the world is their market. WeChat Pay is unfortunately controlled by the Chinese government, and you need to link your bank account in order to use their service. Also, there are some very small fees attached to each purchase.
So, NANO is essentially WeChat Pay without fees, even more instant, and not controlled by a government (aiming to eventually fully decentralized as now one can argue it hasn't hit that point).
Here's a tagline from the devs:
"Our only goal is to meet our mission as stated earlier, to become "a global currency with instantaneous transactions and zero fees over a secure, decentralized network."
This is a massive opportunity for you right now. What are you waiting for?
