I used to think like this.

Until I realized it was incredibly cynical, selfish and self-centered.

Not everybody has the same motivations, and this is not a zero sum game.

I love coding.

And I love even more teaching other how to code and help them get to where I am.

Coding is not sales or trading and I didn't intend for this aphorism to apply to programming.

If you know a stock is going to appreciate in value and you tell everyone about it, they are going to buy it and cause the stock price to rise. If you didn't buy any and they did you will miss out on the appreciation. Alternatively, if you buy enough of the stock and don't tell anyone that will also cause the price to rise in value and other people will miss out on the appreciation.

Teaching someone else how to be a better programmer does not diminish your market value as an engineer in any meaningful way. It most likely increases it. Disclosing your winning trading strategy will make it so you can't profit off it because your trading costs will rise to such a level that the trade is unprofitable.
