I was just reading this
quite good document about bitcoin written by a Yale student. In this document, the guy describe many of the possible ways bitcoin could fail.
It is the best critic of bitcoin I have red so far.
So, could bitcoin fail? Yes, it could.
But you know what? The current financial system has shown us so many flaws, so many disgusting priviledges for a few
too big to fail corporations, that I just want to give bitcoin a try, even if it might be risky. I just don't want to hoard any national currency any more.
Someone wrote somewhere something like : "Current financial system is completely messed up. Give geeks a chance."
That's exactly the spirit.
