I am of the opinion that bitcoin's value in dollars will shoot up like crazy! Bitcoin is used by people (at least some of them!) as an investment and as a hedge against inflation. It is the new gold! So yeah, bitcoin will appreciate even further in value and more people will start to use it.
I don't think I can agree with this at all, you have to think that in its current state a ton of people in Bitcoin is being used by people as an investment with the money that they can afford to put into it. If the global economy and financial institutions were to have a crisis people would pull this money immediately, as they need it for their real lives.
People would pull out the price would crash and then most likely come back up, but who knows.
Some very interesting points here. I would have to agree that it would crash BUT it might just depend on two important factors, 1- how mainstream bitcoin has become. So if there is some serious real-world use there, then people might turn to bitcoin during the crisis. #2 - The cause of the crisis. If it's got anything to do with the banks for example, the world might finally come to its senses and turn to a decentralised economy. But who knows.
