The big crash was already happened,and now time to seat back and prepare yourself cause bitcoin will absolutely fly to moon in no time.
I also believe that bitcoin wil fly to the moon but honestly this is hard to predict that. it is also possible that bitcoin price crash again in comming days.. lets see.
Nothing will happen to bitcoin, I am very sure those that are saying so are the ones may be that do not have any bitcoin at hand, hence out of envy or jeousy they keep predicting the fall of bitcoin. I keep telling this people they should better get their acts together and do the right thing of investing to make money or they regret later.
If somebody does not have any bitcoins or many bitcoins and they want to buy more, they will try to talk down the price.
If the price will go down and crash soon for new and investors it will be the right time to buy bitcoins again once the price of bitcoin was crash.. the price will not stay in low price it will rise again back..
But i don't think that any big crash is coming as anyone say that, because recently Bitfinex hacked, and many person call that is a big crash for bitcoin, but now we can see bitcoin is still in a good condition, so the crash when come bitcoin price down and after some months bitcoin again start to rise. But you are right, buy the bitcoins when price down and save them.
