History of bitcoin price tell us that, it will hit $1000 any day. But not soon.
Why?
I don't see any reason why it should.
Nor it should not.
Bitcoin might fail before reaching 500 usd.
It's still a beta.
Well bitcoin actually was only developed as a proof-of-work. It wasn't optimized for public use. That is why there's usch a huge blockchain size, why it takes so long to download it and why the transaction take pretty long to confirm (the funds in them to be ready to use without any problems).
