One of the biggest drivers of the Bitcoin price are low worldwide interest rates, leading individual investors to bet on Bitcoin.
not exactly. lack of interest doesn't mean individuals are betting! the individuals are still individuals with their own opinion. and those who have high individual interest invest in bitcoin with a strong force. but it is not yet a big percentage of the world.
and as for manipulation it is not because of lack of interest, it may be at its peak but as long as the exchanges are not big enough to be able to absorb manipulators dumps things will remain like this.
I think stock market crash would effects the bitcoin price because people sell the stocks and search for another investment, like Bitcoin
true, but the effects of it is not that significant to be considered a thing in my experience.
