If Bitcoin would die tomorrow then my will to continue using Bitcoin would also die because I do not see a reason on why to keep hanging on to it.
I would go on with my live and just be happy with the money that I have made from Bitcoin so far.
On hearing any rumour, please do not stop using bitcoin like you have mentioned. Whenever you happen to hear any bad news, you must look for the root cause of it and any possibilities that to happen.
In my opinion, bitcoin will never face such any bad incidents as bitcoin is supported by very strong team of devs and financial experts. We never need to worry about the survival of bitcoin system.
