You shouldn't base your predictions on history. For instance in the history of the world there were never any world wars, until there was one, and then another not long after.
Bitcoin might recover beyond its peak or it might not. You can't predict that! Previous crashes were from lower value, with less people involved. At some point it will have to stop growing or it will reach millions of dollars per coin.
I somehow agree to your argument here, that we should not predict any future events based on the past! That's true for real world and the example you have given here. I can also add to it, that there was a global financial crisis in 2008 but that doesn't mean it will happen again because we have learned from it and moved on. But when I talk about technical analysis, it gives me a different picture all together.
This particular chart type is know as "Bullish Symmetric Triangle" in technical analysis. This is exactly what OP is talking about. The representation is similar to the below chart,
As per technical analysis coupled with trend analysis, once the price moves beyond the breakout point, a sharp increase in the price follows. So lets just hope that it happens. I know that technical analysis means very little in bitcoin and crypto market because of its nature. It's the raw reflection of human emotion around the world and it is very hard to predict the future. But technical analysis is just a tool for speculation and nothing else. I believe we have many bitcoins in our cold storage and if the price increases, it's good for all. Lets just hope for the same, even if history repeats itself!
