Probably buy more
That's too risky and possibly we are on the "end of the end" history of bitcoin..
Exactly. Others want to have such a low price for bitcoin so that they can even buy more. They didn't think why in the first place the price will reach that $1. That's a total failure of bitcoin if ever the price will reach that range.
I doubt bitcoin can make it to the top again if ever the price will dropped to $1. Imagine for years with the support from the community still the price will suffer that kind of state.
