What are your thoughts on bitcoin as it just made a new high at $15000 USD?
Well, as the Book says, there is no new thing under the sun. One can simply look back a few years and spot a similar development in the bitcoin price chart.
The channel highlights the "healthy" price range, while the upswing above the channel shows a "mania" stage. The mania lasted 10 months last time, before gravity invariably pull it down. Today is almost exactly 4 years after the last peak.
