Bitcoin bubble / dotcom bubble. Are they really the same?

Howard Marks, who famously predicted the dotcom implosion, warned investors to stay away from cryptocurrencies. He compared them to similar “bubbles” of the 17th century Tulip mania and 18th century South Sea Company. Marks is hardly the first to dismiss Bitcoin’s epic rise as a mere bubble – the economic term to describe a highly-positive situation or environment that is unlikely to last.
