It's a "fixed supply" of something that's very divisible. The media loves the fixed supply narrative, but it's really not important. Other coins have permanently inflating supplies and their charts mostly match the bitcoin chart.

The real gift of bitcoin is that it jump-started a wave of innovation by birthing "cryptocurrency". Once people saw that money would flow into bitcoin, people started new projects to try out all the other now-obvious ideas for cryptocurrencies. People want to build important things.

If you're thinking of bitcoin in the mindset of beanie babies or building a better credit card, then you may have missed the bigger thing that's happening. It's becoming obvious, to me at least, that cryptocurrency is trending in a direction where it will profoundly disrupt any industry that uses the internet, beginning with finance.

Also, I've been following this thread, and you should probably re-read all of vmception's comments. IMO he's right about some important stuff that your replies suggest you may be missing.
