Many people do not know this but he still holds the stock that he first bought as a 13y old. It is now worth 8+ figures!
I've read this years ago in "The Warren Buffett Portfolio", but couldn't find a definitive source for this response quickly, so here (https://www.fool.com/how-to-invest/2014/03/15/the-very-first...) is the reference I used to recount the details above.
Should have treated it the old-fashion way, not the modern day-trading way.
Buy and hold is a hedge against inflation as good if goods increases the the stock reflects the relative expansion of the money supply.
Also some shares pay dividends.
so the point is protecting your wealth against inflation and continuing the compounding over long stretches of time.
you can liquidate as required or even borrow against it like the very rich do.
