If bitcoin drops to 1 dollar, ill buy more and invest it till the price increase
if it goes to 1$ per BTC then do you think it will rise again and you can invest when price increase??
think twice
I will believe if there are another people will say to think twice, for to do that, because it seems like the coin in front of their hole of dead and in my minds investing on them is between alive or dead.

For me it would very hard to buy Bitcoin again if it dumps it price very low. It's normal to us to think that maybe we should buy or not on the current state of Bitcoin since you won't know if it rises again or dead forever and maybe that time there's a new crypto would exist and replace Bitcoin to its place. I'm just saying my opinion.
