I will call this a 'wishful' prediction, it is not unusual to read about such price prediction, we all have different points of view, and if some persons believe BTC price can surge as high as that, then that is fine. However the reality is that we are very far away from $1 million for 1BTC, the price moves organically and to get such a price must be sometime down the years, no matter what happens to the banks or to fiat.
