Exactly what the title says.
If bitcoin dropped to the price of a dollar (which we hope it never will), what would you do? Buy more and hold, sell? Buy a promising altcoin like ETH?
I personally would buy more bitcoin.
I think that this will not pay off even in a nightmare. If so bitcoin falls, it will be a terrible panic market.
That's true people who have invested lot of money in bitcoins will surely get panic and even go bankrupt if price goes to that low level in future and it will completely destroy bitcoin as a currency.
