Internet Explorer is probably the lamest, or one of the lamest web browsers out there but still, the most commonly used worldwide.
But what do I mean here? Regular everyday normal
mot**** people don't like trying something new as long as what they already know works fine enough.
Now think about all the worries that bitcoin brings about in terms of security in the minds of these people who'd like to keep it simple? Well you've got your answer: people won't learn how to secure a computer just for the sake of something they don't feel like needing.
Now that might be because I'm from a remote countryside with a rather conservative background, but still, I truly believe that people think of bitcoin as being too much of a hassle, while their own everyday currency/banking system works fine enough in their minds (and I'm talking about the Euro here
).
A lot of changes in mentalities will be needed before bitcoin can start to have a ghost of a chance of success with these people.
