THE 500K $ Bitcoin scenario

If we are back on some kinda like 2008 scenario we can imagine some possible trends
USD cp = 21.2 trillion atm
BTC cap = 451.06B$
According to pure speculation about the future I can immagine a bull scenario starting next year or sooner (maybe some spike at 6/3k before would be great)
A bear scenario would include more world bad news, regulations and the some tecnology shift
