On the down side, it is not clear that the market for coins is liquid, and it is currently not widely accepted as tender, and may never be in the US/Japan (whose Central Banks/Governments have the most to lose with loss of control of money supply). But in spite of this, or maybe because of it, I think the future for Bitcoin is bright. When we see hedge funds becoming market makers in Bitcoins I think it's time has arrived.
Bitcoin encourages people to KEEP their bitcoins. Why use them to buy something when next month they're going to increase in value.
Particularly, so long as it is preceived to be likely to increase rapidly in value, it encourages them to use bitcoin as an investment vehicle rather than investing bitcoins in other things.
Obviously, if you want to consume things, you need to liquidate some assets to consume them, and if you've tied up your assets in bitcoin, you'll spend them for consumption.
There's not that much friction to exchange it for currencies. I just transferred a five-figure USD amount to an exchange, sold it for BTC, sent them to another exchanged, sold BTC for Euro, withdrew it on the other side of the world. All of that through two exchanges based in countries I've never visited. I saved enormous amount of money compared to just wiring USD -> Euro through my bank.
