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.
Well because price wouldn't drop to 1$ in 5 minutes, so when i would notice that price drops, i would sell all or some of my coins, so i would be safe from losing all of my money in bitcoins, so i would be pretty safe
And when price would be that low like 1$, i would probably buy like 50 or even 100 bitcoins and i would keep them till price will rise, and i am pretty sure that bitcoins price would rise back, price of bitcoin always rises after price falls
