If bitcoin dropped down to that value then at that time I will not have any coin as I will start to sell all my coins whenever I feel that the price will now go down, and in that time if someone will keep their coins with him then he will lose their money.
Hey,wait it maybe bitcoin price is halving only for short time and next time will go up again. I think to hold your coins is better than you trying to selling this. because we know after bitcoin price is halving and will happen to rise in next time.
The price of bitcoin is depending on it's demand, so if the price of bitcoin drops to $1, Many will just dump it. And still there are some people who are going to try their luck to purchase more and more. So, somewhat it is balance with that kind of scenarios that are possible to happen. And in the end,
there's still going to price increase because there are people who are going to buy.
