I agree with the fact there is no trust and honesty in the system.  When it comes to bitcoin, there are not enough people using it to make it a norm in society.  Because of this, it makes it hard to spend it in public.  Then you have the scammers who are always setting up scam investment sites in which there is no one policing them.  Start up a USD scam site like some of these bitcoin investment sites and see how long it takes for the FBI to come knocking at your door!
