Market Crashes had occered in the past and its gonna happen in the near future but btc to think like btc to be valued by 0 will be  a foolish thing to think. Bitcoin is an opportunity for people and its a service which is now being admired by users.
By supporiting btc I am going to say btc is never going to bite the dust however I might will be eagerly waiting to see how btc how far it can grow. Cause simulated knocks are regular so..dont rush to any judgement before you make any contributions. If you decide to invest dont panic if value falls..watch the market and keep your patience in any event for some time then make the decision.
BTC IS A System And a system never dies it just changes the ways.
