I have a generous pension and 401k which have allowed me to take quite a few risks with my individual stocks. I only hold very few stocks. Properties, pension and 401K aside, I consider all the remaining cash to be a gamble. And this is how I ended up with CTSO, I gambled on it and threw sh!@load of cash into it. If I had to go back 20 years, I would have stuck to S&P 500 and nothing else.
To answer your question, I am not diversified with my cash whatsoever when it comes to stocks, I gamble, that's what I do.
401k is a different story, I am doing it the good old fashioned way. Slow and steady, minimal risks.
I have also gambled on Crypto, that didn't turn out so well for me either. I am very good at entry points but I suck at exiting. I enter, ride it to the top, and go back again to where I started, or lose my shirt.
