It is a clever hack, but it can never work as money. The money supply needs to roughly match the size of the economy. If there is too much of it, you have inflation. If there is too little of it, you have deflation, which in many ways is worse. With Bitcoin you have too little of it, because the total amount is limited, and that limit is smaller than economic growth is. That's why Bitcoin's price as compared to major currencies has soared. But people who used Bitcoin years ago to buy pizza feel really stupid because if they had held on to it, they would be much wealthier today. When it works that way, it isn't money. It's a mathematically interesting investment vehicle, perhaps.
