I applied to be a Meituan rider today and got rejected.

The HR manager told me:

The most unreliable ones are you crypto traders. You've applied several times, spent all that effort, and then never even showed up to work. You apply once every so often, and it's always concentrated applications.

We get delivery riders who blew up their crypto accounts. Right after they start, every single one works like crazy 24 hours straight without rest, then once they make some money, they quit. They say they're "taking off to the moon," and then a few days later a bunch of you apply all at once again.

In comparison, the delivery riders coming from A-share stock trading are much more reliable. They stick around for several years at a stretch and work steadily and conscientiously.
