There will be a price correction once the pump has been over and we should be expecting around $1000 - $2000 price correction given how much the price has increased. As for bitcoin crashing, I don't see that happening. I mean come on man we all know that bitcoin is highly market oriented and it will be there as long as people use it and there are people mining it, people would probably even use it even after all the bitcoins have been mined. There will be big dips but I don't see bitcoin crashing, at least not now or in the next 25 years.
When people buy bitcoin for investment purposes and not as means to transfer funds, then this "investment" takes a different route and instead of becoming the "Anonymous PayPal" that would be in the future - it turns into a ponzy scheme.
The product can serve well for 20 years but when "the market" (miners, China, those who decide to approve/disapprove forks) is turning things in a shady way - then you can certainly expect them to be shady.
