I think this is one of the most powerfull reasons to the people to not believe in (at least the people who know a little about that because in the main stream media you'll not get much info) and also there is a lot of problems to solve like what hapend when a user dies and he/she is the only who knows how to get into the wallet? there will be a lot of dead coins in the chain that no one will ever have access? If all this types of cuestions not have answer soon I think it will be very difficult to make the changes we all are hoping for. great post, following you for more!
