first: we have to figure out the rock bottom!
So in case bitcoin bounces off somewhere between 5$ and 120$ we could look at this question again. Before finding bottom: useless idea even to think about 'what if'
Bitcoin is a reflection of society...a walking zombie.
And society hasn't even arrived ... these are still the more intelligent zombies these days ...
This is almost impossible.
1 most coins are held for the long term
2 As the price drops then it becomes more attractive an investment
3 Far to much money will flood in to buy BTC well before hitting $100
I will caveat this with one proviso. Underlying Bitcoin technology isnt found to be totally flawed ( As it is open source and been under the microscope of pletny then this is very very unlikely)
So may I suggest you put forward reasons why it will go sub $100 without a flood of coins being bought?
