First of all I admit that I do not have knowledge in regards to bitcoin network. I just want to point out some concerns regarding security.

On my knowledge, bitcoin makes our transaction secured and anonymous. We are aware that before we can make transactions we need a wallet and there are lots of sites that you can get one. Some of these sites requires registration which is totally fine for me. My concern is that, some of these sites requires me to "verify" my identity by uploading government ID's, address, pictures and any other document to personally identify me.

Do you think this requirements ruin the purpose of having "anonymous" transaction over bitcoin network?
