That might be a theory that cannot be proven with certainty. Bitcoin does dominate market capitalization with numbers that can reach> 50%. So the problem of $ 7000 / $ 6000 for me is not too much thought, the point is Bitcoin is strong and every time the price drops, it will rise again.
Bitcoin was getting strong from the last month, and although right now, we do not see the very highest price, it will increase to the highest price, and we don't have to worry for that. Bitcoin will make people amazing of the movements, and they will start to buy when Bitcoin has started to increase. And for people who already have bitcoin, they can start to sell some bitcoin to make a profit.
