On June 8, 2011, the same day Ars Technica ran its first story about Bitcoin, the peer-to-peer digital currency's value jumped to an all-time high of $32. Bitcoins had been worth less than $1 just two months earlier, and that day proved to be the peak of the bubble. The value of a Bitcoin fell below $20 within a week, and by November it had fallen to $2.
But since it hit bottom late last year, the cryptocurrency has defied skeptics (including me) who predicted it would prove to be a passing fad. The currency regained some of its lost value, and the price has become much more stable in recent months. In the last three months, the value of a Bitcoin fluctuated in a narrow band from $4.50 to $5.50. As this is being written, the currency has just hit a 3-month high of $5.60.
