I am actually very wary of giving away an image of my passport. Some Kyc allow you to give ID instead, but that doesn't prove citizenship. I think there are a lot of ways that people can sneak around the KYC process, if they want coins, they'll find a way to get them. Some people will go above and beyond what is legal to make money. For me, I have to really really trust a team and a business model and a coin to send in a photo of my passport. If they leak it or sell my info, i could be a victim of identity theft.
