$1,000 per Bitcoin would be too hard for people to buy and sell them, so I hope it doesn't go that high actually.
A Bitcoin is divisible by 100,000,000 (called a Satoshi) so the rising value of Bitcoin will likely never become a problem.
I would be happy if it reaches $1000.. Offtopic : can any of you guys tell me on what basis does the BTC price increase ?
It's a case of demand vs supply. Demand can be affected by many factors of course and if it were easy to predict, I'd be a wealthy man.
Anyway, I'm just making my first post so that I am allowed access to the rest of the subforums. A slightly annoying restriction, but if it stops spam/bots, I'm all for it.
