I went to check out some sites- Coinbase, Bittrex, Coinex CEX- The first three asked for too much of my personal information. CEX does not work in New York State. Eventually, I gave up for good.
There is a difference between sending someone your debit card number and sending a photo of your id card to a total stranger who you can not see. If I could meet someone from Coinbase and actually show him my id card. that would be different. I am sure there are people who use the web for email and youtube videos, but even buying over the web- actually putting in your whole credit card number- is too much, so they never buy online. It depends on how safe someone feels online and how much information they are willing to share. I, for one, feel very uncomfortable sending someone a photo of my id over the web and I will not if I can help it. Sharing photos of me? Sure. Sharing photos of my id cards? Forget it.
