If you aren't willing to put in the work, sure just hold an all weather portfolio or whatever. But I don't think it's super hard to beat the market on a risk-adjusted basis, especially as a retail investor. Most of all, it takes a passion for it (trading is a hobby) and also a reasonable amount of time dedication.
For example, there are a number of persistent factors that don't go away. Things like value, low-beta, size factors, etc. It's not super hard to leverage the tons and tons of papers that have been published to construct a portfolio that does really well. And, due to structural reasons, will do well until the laws change (almost all persistent factors exist due to some law).
Especially in the current market environment, it's really easy to make a killing. The market is moving purely on sentiment and day traders have had some really great opportunities to make stacks in the past couple of months.
Comments like this are why these "beat-the-market" threads are evergreen on HN. They do a disservice to the community.
Real estate is another area that is very typical for bubbles and when the bubble bursts the large majority of people who are overleveraged will be eaten alive by the big investers (much bigger than you) who make money off the poor in times of crisis like they always do.
Since it was very hard to lose money with cryptocurrency even if you tried, you had years where it was a good idea to invest. Who should you listen to? The one that got rich with a better scheme than buy and hold? or the one who sat on the side lines for years, made zero profit, and now holds a grudge at missing such a good investment?
Poor people should not go into real estate. There is enough for everyone. If you'd put some of your wealth into Euro, in the past months alone, you'd have made enough to buy a small apartment when the bubble bursts.
Good luck with that though.

I think your attitude of dismissing decades of academic research by Nobel prize winners is a little myopic.
Also I don't think you understand what "risk-adjusted" means.
You might be right; why don't you try explaining it for me? I suspect it is going to look a lot like a justification for why your strategy is fantastic even though it makes sub-par returns.
I can give you complete run down of persistent factors, leverage, risk-adjusted returns, etc etc.
That will lead you to the reasons why it is very possible to both beat the market and be incapable of scaling it up to billions of dollars.
tl;dr: Someone who has found a way to reliably arbitrage to 25% gains year over year on an inefficiency that will only fill about $100,000 is not going to be able to cash their system in for billions of dollars. But they will be reliably beating the market (on a risk-adjusted basis: assuming the system has risk equal to or less than holding e.g. the S&P).
You will find that firms which can actually reliably beat the market do tend to make their founders wealthy. But they can't scale it beyond the capacity allowed for by the inefficiency. All successful hedge funds and prop shops eventually reach a point where they can't reinvest the returns for the same gain.

But yes, picking stocks is probably not as effective for most people as buying an index fund.
I doubt he could without using or BH insider info.
