In early September, one Bitcoin was worth almost $5,000. Then the Chinese government cracked down on cryptocurrency investments, and Bitcoin's value plunged 40 percent in a matter of days, reaching a low below $3,000.

But Bitcoin bounced back. By early November, one Bitcoin was worth almost $8,000. Then last week, a controversial effort to expand the Bitcoin network's capacity failed. Within days, Bitcoin's price had plunged 25 percent, while the value of a rival network called Bitcoin Cash doubled.

Today, Bitcoin has recovered all of last week's losses?one Bitcoin is now worth more than $7,800.

Bitcoin's recoveries haven't been very surprising to long-time Bitcoin watchers. Over and over again, Bitcoin's value has seen spectacular plunges only to recover the lost ground and rise to new heights. Bitcoin has seen at least three major Bitcoin "bubbles" over its seven-year life.
