The Coming Echo Bubble

One of the greatest traders I know has privately been talking about an Echo Bubble that will be coming in 2023 before a crypto winter for the next decade. So what's an echo bubble?
An echo bubble is a smaller (both in terms of percentage moves and time) bubble that follows the drawdown of a much larger bubble.
Here's an example of the DOW during the 1929 crash that lead to the great depression. There was a period of time lasting almost 8 months where the stock market continued to increase.
Since there's not really a scientific definition, this type of market behaviour is also referred to by many other names such as a bear market rally and dead cat bounce.
The point of this post is to tell you that the best trader I know said that an echo bubble is coming. Until then we wait or at least try to wait and not get rekt by sam.
