Looking at the history of Bitcoin and saying “Wow, the price of Bitcoins will never drop because it hasn’t dropped so far” is like looking in the back mirror of your car saying “Wow, there will always be a freeway ahead of me because I have been driving on the freeway for so long now”. The fact that is has flourished can have a million explanations, where one is that it does actually have a long term viability as a currency. We do, however, not have enough information to say with any certainty that that is indeed the case.<p>What we do know, is that so long as new users flock to the currency there is an increasing demand, and this will drive the price up – until the recruitment halts. Then what will happen? We don’t know. It might disappear, it might drop slightly, and it might stay the same. That will be the true experiment. Right now we don’t have enough data to say whether it is sustainable over the long term.
