I do find it odd that they are asking for more, I mean Facebook and Amazon are global companies but they don't ask that much for a KYC, I am sure that they are the 4th one that @mk4 is pertaining too.
Yes, but one is a social media platform, one is an online shopping platform, while cryptocurrency exchanges are finance platforms that involve
money; anti-money laundering and all that jazz. It's just expected that cryptocurrency exchanges and finance and investing platforms in general to be a lot more strict with KYC.
