I don't think there has been any recent news that would have resulted in the recent collapse of bitcoin's price. Quantum computing may ultimately make bitcoin infeasible, but it's not driving the price right now.
It's not exactly clear what is driving the price drop now. It seems to be a bunch of smallish factors, magnified by the usual bubble market feedback effects.
For any other security, you'd say that it would eventually recover after a correction. For BTC, it's not really a security, so it's hard to say where it goes from here. It's based solely on collective buy-in.
