Few months later, after crediting bitcoins to an exchange account...
I: Why did you set lower limit of withdrawal from 100BTC to 0?
Binance: Documents we have are not enough, please, send us your video.
I: I want to stop working with you and withdraw my bitcoins.
Binance: send us your video.
So they're asking you to send a video, is the video about you logging in your account? If that's the case, why not follow the instruction? It would only take few minutes to do it and you'll get your account back.
Here's a
thread where a user was also asked to send a video, their support and staff replied in the thread saying screenshots aren't enough proof.
