Or to put it another way, "do you use bitcoin?". People who use bitcoin are trying to convince themselves and others that it's not a bubble so that the value of their bitcoins continues to increase. It is a bubble though. It surprises me that people still fall for quasi-pyramid schemes and the promise of ever increasing value. How long do you honestly expect this to last?
At the moment it's mostly pyramid scheme. While useful, it's clear Bitcoin's value has become disconnected from it's utility as a currency.<p>Perhaps a more interesting question, can a new global/digital currency gain widespread adoption without massive deflation? Bitcoin has deflationary features, but the recent increase in values is mostly just a lot of people pouring into the currency. How can a distributed cryptographic currency be designed to get around this problem?
