I believe Robert Kiyosaki has his point. But relying on predictions, and hoping for higher prices of Bitcoin is quite unreliable.
Nothing is guaranteed in Bitcoin Market of course its full of predictions, emotions, fear, allowing ourselves move along rather than wanting to move every step before price does helps keep us in check with our investment choices. In essence don't buy or invest by bypassing your rules and Model because of Some else.
Most ill-informed followers might jump in to to invest now, and loss because of such hype.
Bitcoin to $250k is a probability nobody can truly tell it just a pure guess, our main control only applies in our Bitcoin Portfolio and decisions.
I mean, $250k is pretty moderate forecasting, I heard he's so bullish back then going as far as predicting bitcoin to reach $1m within few years, that coming from few years ago.
but right now, even if you get fomo'd and invests right now, I don't think you're gonna be losing as long as you hold for long, when someone like robert kiyosaki talk about price reaching $250k, he usually disregard volatility because it's just nothing but noise when you are holding for long term.
so in my opinion, his speculation about bitcoin reaching $250k is pretty normal and harmless.
