if that will happen i will buy bitcoin as many as i can. because i think all or maybe many of us has same mindset like me
Are you sure ? If bitcoin price dropped to $1, something big must be happened and makes people to not use bitcoin anymore. If you buy bitcoin on that price, it might have a big risk to do that.
I am pretty sure that if the price of bitcoin is going to drop to $1 many investors are going to buy a lot of bitcoins especially those people who are believing with bitcoin and I know that they are going to buy as many as they can as long as their budget is enough for it. So that it can give them good profit when the price is going to increase.
I think it wont happen since those investors for sure would have lost its trust already to bitcoin when it drops its price too low. If they are big investors in the past when the price of bitcoin is still $600_ mark then for sure they would panic as the price of bitcoin decreases day by day until it reaches $1 and thats already a big loss to them. They would have a second thought or a hesitation if they would buy more or not.
