Bitcoin has nothing to do with the economy
Not entirely correct. A bad economy or bad news in the economy has effects on the bitcoin market. It is impossible to pin one event to one bull/bear run but they usually occur parallelly.
Dont forget that in economic collapse, people will be trying to survive and not use the internet to spend bitcoin to buy stuff, it will be bare bones fiat or gold. You would rather sell your phone and laptop for food.
what we should be asking ourselves is when to invest on Bitcoin getting proper information so people don't see investing as a scam
Investing in bitcoin should be at the lower ranges of price. This range depends on years of observational data.
