Speculations is the best thing to rely on when the next direction of the market is uncertain but I think Kiyosaki is going off point. This is not the first time many have predicted tbe price of bitcoin to hit $1m but till today, we are yet to hit $100k target since launch. I'm not saying it's not possible but when making predictions, there should be corrected factors. Too much dependency of predictions will live you disappointed and with time, your talk will be of no use to the public, only talk when you think it's necessary, not figures that are unrealistic.
Why we must rely on the speculation? As far as I know we mustn't rely on such thing like speculation. 
Sure, crypto market is always difficult to predict. There is no certainty in crypto market direction. If crypto market direction is predictable, people doesn't need to speculate and everyone has a guarantee for success in crypto investment. Uncertainty is the nature of crypto market, everyone must know it, dude.
Regarding Kiyosaki's prediction, nothing wrong to predict Bitcoin to hits $1 million. I think it is not something impossible, it is very possible. If Bitcoin never hits $100k, it is because we are still in the bearish season. Why we expect for a new ATH when the bullrun season isn't coming yet.
Even with Economic harsh, we shouldn't forget what has happened last bull run, you can't expect the next bull run to be smooth if we don't address why the bitcoin has collapsed back to 15k low after making all time high od $58k, the price will still collapse even if there should be another bull run because of trust issues.
Economic harsh? 
What we forget about the last bullrun?
I think everyone must remember it, Bitcoin hits $69k in the last bullrun.
I don't know why you seem too pessimistic, I think you have no reason to assume the price will be hard to raise in the next bullrun.
