We are automatically comparing a bitcoin with a dollar, and wonder why its so expensive in compassionate.
But what if a bitcoin was called a bit kg of gold?
Then $240 is cheap - and considering that nobody outside this forum and a few internet sites even knows anything sensible about bitcoin - This could run for at least another 2 years before we get to a point where people stumble.
I really can't see anything stopping it going up for at least another 6 months - even if it does slow down a little!
The price of bitcoin is arbitrary. It doesn't really matter if a single bitcoin costed $ 1 or $ 1000. Because that depends only on the number of bitcoins for sale and the demand.
The problem is the unmotivated, ridiculous growth of the value. It's not sensible with this current growth rate.
