Probably buy more
That's too risky and possibly we are on the "end of the end" history of bitcoin..
I don't think the bitcoin's price will drop down to this cheap price even in the worst cases, but if it happen that will be great opportunity for the Bitcoin's holders.
Though it's hard to imagine that it would happen this time, but maybe, just maybe, it is possible, for some it may mean an opportunity, but for me, it's not...
If bitcon dropped to $1 then its most likely that bitcoin would be declared dead for the last and final time. I cant fathom it coming back from something so serious and trust me, its going to need to be something super serious in order to get btc to $1.
yup, it needs too much pressure to pull it down that low, but for sure, we are one of the responsible for that downfall if it really happens, we are part of the system...
