This could be the case in the future if investors begin to see bitcoin as a store of value but it seems we are not there yet, investors see bitcoin as a highly speculative asset and as long as this is the case then whenever the stock market goes down significantly we may see an eventual movement in the same direction of this market, many do not like this but to me this is a transitional phase of bitcoin and there is nothing to worry as long as the development of bitcoin continues and fiat keeps losing value.
