It's not. I use bitcoin to pay for a few online services, including my hosting. I love it. It would be absolutely awesome if bitcoin succeeded, even if the price remained the same (I know it's mathematically impossible, but still). A currency that no single government/entity can stop or freeze. A currency that no government can dilute. It's kind of like digital gold, except the amount of gold in the universe is practically unlimited.

Bitcoin's value comes from it's acceptance and worldwide capability.

There's nothing that can allow you to move money to every country on the planet with such small fees.

However, you are correct. In order for Bitcoin's price to increase, people must value it and more people must use it.
