Nothing will happen to bitcoin, because Bitcoin has very strong support at 6000$ and it's very unlikely that the price could go beyond that limit. By the way even if price went a little bit lower than we expect, it will only attract more investors, what would be good.
It seems people have the wrong notion that the price can keep decreasing and could reach zero but we know that is not going to happen, as soon as the price goes lower than 6000 people see this as an opportunity to get bitcoin, that is why the price does not last long at those levels because people take those low prices as buy signals and the price recovers because of it.
Bitcoin has a very strong position in the market, in fact the bitcoin users are increasing from time to time, people interest in bitcoin is continuously increasing and therefore we can hope that bitcoin value will also continue increasing from time to time, I hope very soon we will see bitcoin price crossing 100k.
