Yeah I wait it too.
But I think if 100$/BTC the price is only getting down, not getting higher

yes, very few people will have interest to invest in bitcoin anymore, I don't think the bitcoin users can handle another crash. So many people who bought at 1000$ will be heartbroken to see their investment value at 10 percent now. I think if hits so low, there will be no point investing in it, I would definitely get out of the bitcoin world if such a situation takes place.
