Bitcoins are just a right to participate in a digital crypto economy. They don't have any value in themselves. Its like holding passes to a show in the big theater. If the show doesn't start you passes are worthless. If there is any meaningful possibility of a show in the theater, you might get lucky for holding those passes. The main problem is that people who will participate in the show also need to get the passes to actually act out the show but if everyone just keep holding their passes for no good reason, well then there may not be a show.
From many bitcoins forums, people are hoping that its USD rate climb to $1000 or even $1 million, which is pretty ridiculous. People who have thousands of bitcoins, can probably keep holding on to them after selling 50% of them. But people who gonna buy it for more than $100 , they gonna panic at a first sign of decline. I suspect its not that far off.
