I agree with the principle but feel that it’s easily said than done. Applying it successfully means that you got to manoeuvre your life in such a way that you get intimately acquainted with one asset class. Warren Buffett bought his first stock when he was 11. Robert Kiyosaki made a killing with the real estate market. Honestly, money doesn’t hold that much of an appeal for me. I spent my 20s n 30s travelling as much as I could n never regret it.
The subtext in your question is whether one should go all in on Bitcoin. Again I have my doubts honestly. It’s trustless n permissionless, but I feel that there are larger forces beyond my control. What if MircoStrategy goes all out to acquire a substantial percentage of BTC? What if more nations make BTC their national currency? What if the ETFs grow exponentially n suck up all the BTC like a black hole? I don’t fancy submitting to just one thing because it implies a loss of control for me. I’m blessed that I trust my National government enough to invest in its bonds and T-bills haha. Diversification is for me the pleb Sensei!
