Bitcoin is a currency AND a payment system!
The payment system (and tracking system) part is the part I think people will copy. If they do, the currency part of MSC will be threatened.
Ripple is a far superior payment system than Bitcoin.
Again, look at it's price!
Look, I have to sleep and English not my 1st language so I can't post like I want to.
But you have a digital technology here - the question is if Bitcoin is the new Myspace or the new Facebook.
The same applies to MSC too and probably to all digital networks.
There can be only one (real big).
If it is not MSC, then maybe it will be something similar - but you HAVE to have 1 as the big guy.
The first mover has a big advantage.
