I find this all to be such an amazing concept.
However unless it is someday somewhat connected to the real life ( i.e. regulated to some extend ), I find it hard to believe it will end up being the currency/coin of tomorrow for everyone (at least as is).

How can you use it to buy actual goods on a regular basis if the value fluctuates in such a way that it does currently?

So at the moment this is "just" to me an intrument of speculation before it turns out to get mature  (which I have no idea in which actual shape).

Having said that, it is not mainstream yet so I believe it will go up for some time again, but I hardly believe it will reach $10000 as is.
