It's the first time I hear about video call for KYC verification. As for me, I wouldn't be happe to pass it. It's better to forget about some coins. THis video can be used everywhere later.
I made a video call, but not for a specific project. There is a special application on the phone. I read about it on the Internet, it is certified and works even before the ICO. I thought it was convenient, because two minutes of conversation and KYC procedure was passed. It is very convenient.
