If by stingy they mean only some that has a very tight hand to hold can invest into bitcoin then I will say they are correct, for you to be a good or profitable bitcoin holder, the urge to sell at every slightest opportunity should be something you need to control, this doesn’t in no way means you just hold and don’t take profit, No you can set a take profit target and when the price gets there you take some profits and then invest into other businesses or assets for diversification sake this will even give you more income to buy more future dips.
Looking at the tips you listed i will like you to add the one ultimate tip which never invest what you cannot afford to lose even if the assets is having a good history like bitcoin, investing in what you can afford to lose doesn’t necessarily even safe you from losing but actually keeps you calm even when the price dips and allows you to make better decisions.
