dude you're using bitcoin
therefore you can't be stupid
you just have a weak point

That's true Bitcoin is no where near the stage that it's easy to use and understand and it takes a lot of research and brain power to figure it out.
If you think Bitcoin requires "a lot of research and brain power to figure it out", you are stupid.
If you think it is very simple you either don't know it very well (which is fine btw, you don't have to do so even if you use it) or you are really smart.
It takes literally 5 seconds to figure out how to create a web wallet. It takes 2 more seconds to find your receiving address. It takes another 2 seconds to find your sending address.
There you go, that's 90% of end-user bitcoin usage.
Yeah, so you don't know it very well.
And as I said it isn't necessary to understand it completely in order to use it.
It is very easy to use Bitcoin but not so easy to understand it completely.
