I don't check price data but I assume the base prices for your fall calculations are All time highs. It is key.
- If $64,800 is the all time high for Bitcoin in 2021, ok go ahead with your speculation and comparison
- If $64,800 is not the all time high in 2021, all comparisons above are not relevant
If you want to compare, please compare yesterday Black Wednesday with the massacre before the Segwit in 2017. It is my small hint for you, for this comparison and for future of Bitcoin, just in this year.
