I don't think that the time will come that people would be forced to invest in bitcoin. Bitcoin is for everyone freely and there's no need for any forcing to happen because you can have it as much as you want, voluntarily.
Soon Bitcoin would not be news or in the news as much as it is today.
It will remain on the news, no matter what level of adoption we have already. Still, bitcoin is going to be a talk in the town regardless of the price since it's already in the mainstream and there's dedicated time for it given by those news agency to monitor it.
