but the problem with involvement of fiat is that they will start needing users to verify their identity and submit their documents and eventually turn away some users.
It is unfortunately inevitable change, as long as you are dealing with FIAT financial services then you have to be ready to give up some of your privacy.
What is a little surprising for me is when people seems to not not care about giving all their personal information to banks and refusing to do this in case of bitcoin exchange.
I understand that is because bitcoin exchanges are not so deeply rooted in legal system and history showed that their security system might be flawed AF.
Still I think that blockchain.info will be one of the few services I will trust with this.
