In this analysis I want to take a look at Bitcoin's historical behaviour at the moment that it made new all-time highs (ATH's), and make a prediction based on those findings.
As seen on the bottom two charts, Bitcoin has ALWAYS reversed substantially from the previous ATH's area of resistance (note: the area around the ATH functions as resistance, not the exact value).
2017: ~33% correction.
2020: ~17% correction.
This time it remains to be seen how much we will reverse. Seeing that corrections (and pumps) become less extreme with time, it's likely that it will be less than 17%.
In my view, the most likely scenario would be a reversal towards the first yellow area of support (1), which would be around 11% decline from 69k. The worst-case temporary reversal would be a fall towards the second area of support (2), around 25% decline.
In the long-term I'm still bullish. However, we have to acknowledge that historical price action is against the bulls. On the other hand, this might be the last time we can buy BTC for these price for the next 1-2 years.
