You don't need to connect the history of Bitcoin to NASDAQ or anything else because when you pay close attention to the history of Bitcoin it is enough to predict what will happen even though it is not 100% accurate but at least it will not be much different, the four-year cycle runs as predicted and is great this possibility will also happen after the halving next year, and more importantly prepare ourselves by continuing to add Bitcoin to our bags to gain profits in the bullish period.
Bitcoin is Bitcoin, not NASDAQ and correlation between them is weak even they exist in a same world, share common background like global economics and social conditions.
Bitcoin is unique with its halvings and halving cycle that is about four years for each. Many conditions in each cycle but halving effects work like charm so far. I believe it will continue to repeat but I will change my minds when history has a new rhyhm but I don't believe it will be different than past three cycles.
