But everyone can tell it is much more than that now.......
So~I want to start a new prediction~
Not more than 2000US$/1BTC? Just a wild guess~
From what i see the bitcoin are way too much expensive now , people wont have enought fund to push it up more .
That could be, although as long as there is demand in the marketplace it will continue to rise. At this point people are still trying and failing to even acquire bitcoins on the general market in some places, indicating to me that demand is still higher than supply which obviates further increase in price. Add to that the fact that people are just waking up to the fact that it even exists, which would seem to indicate further untapped demand.
In terms of where it stops, that's impossible to say. That, to me, is a function of multiple events both pro and con. Firstly, the price has to stabilize for it to be more widely accepted as a means of trade. If more global vendors, ebay, Amazon, google, etc., start accepting it, which I think they will eventually, price blows up. Just as in the normal stock market these types of market shifting events will impact price. If governments, banks, etc., try to stamp it out, which in some cases it is likely they will, prices will fall. These types will ultimately fail to control it, however, so long term, as long as bitcoin can maintain it's structure and keep the miners/processors making money, therefore keeping their network running, it is viable and pricing is likely to rise further, as it is a finite asset with further demand to be developed.
