bitcoin price will not drop to 0 because there will always be people who take advantage of the price reduction from bitcoin and will not visit it to buy bitcoin on a large scale and if it happens to eat bitcoin prices will rise again, amid a significant price increase due to large-scale purchase, then there will be people who will panic to go buy without careful consideration and in the end they get stuck at a high price point and when big buyers sell all the bitcoins suddenly, then the panicked people will be afraid to cut loss in the hope that the price will stay up after the correction and in the case of bitcoin prices will persist.
