Having a strategy like "never selling" is very dangerous. Because then, there is no meaning in holding Bitcoin. HODLing doesn't mean that you will never sell your profit. It means that you make a long term investment. And you set a price goal for yourself. When Bitcoin price reaches it, you sell some or all of your profit. That helps you not to do stupid things.
I totally agree with your opinion, maybe we will be the stupidest people, if we continue to keep your bitcoins, while you have nothing else to use as capital for our lives, this is a business, if I get a little profit, it's done. definitely I will sell a little bit of my bitcoin, then I will buy it back when the price goes down..
