Robert Kiyosaki made his fortune from selling "Rich Dad, Poor Dad" book, not by using the methods that are actually in the book. the Rich Dad doesn't exist, unless there is something he is hiding from everyone.
However, he is correct in that the bitcoin price will reach $120,000 very soon. It probably won't happen next year though, but maybe in two years.
How then do you accept his prediction of bitcoin price? he's not fully into cryptocurrency he only uses the traffic to gain more sales or popularity to his books. In my view, he wants to portray bitcoin as the kind of investment people should buy, but you rarely see him talk about the disadvantages of such investment. In his book, he promoted real estate business, not crypto. Why is he flaunting cryptocurrency all over his social media? The floor is open for him to write a well detailed book about cryptocurrency, before we take his predictions and information seriously. I've seen people like him, who take back their advise immediately cryptocurrency price crashes, they'll not say a word and when they do, it'll be condemning the mistakes of investors who invested into crypto. Nobody, can tell or explain how soon it'll take for bitcoin to hit 120k even after the halving. On the other hand, he claims that the rich dad bought some hotels in the US that's still operating till date, have seen his interviews where he said such. The stories in his book doesn't sound like fiction.
There are many similarities between the sentences in OP's thread and the original source, I'm a newcomer here and don't know many things (maybe I missed some rules), but is this not considered plagiarism even though OP has included the original source?
I think your question should be a fresh thread, in the right board, as it's not contributing to this thread. The essence of replying under a post is to add more flairs and value to it, not asking a different question, that doesn't add up to OPs idea or writeup. It can change the subsequent answers under the post, thereby belittling the value of the thread and may not be educational to the readers of the thread.
