Because investors who don't like to sell or who want to continue accumulating bitcoins are people who haven't set a plan to sell they will be more likely to continue buying as they like.
Every investment should have an end, just as every chapter ends. If the investment doesn't end. There is no point in investing, I would consider it worthless. You have been investing all your life, but have not been able to enjoy the money invested. I consider such an investment futile. But I am not saying that you should end the investment too soon. You invest a certain amount and after getting your desired profit exit the investment and enjoy that money and start investing again. You can continue like this as long as you are able to generate income. Build a sizable investment fund years before you retire from your career so you can enjoy it in retirement. If you only invest all your life, that money may one day be left uninherited. Because human death comes unexpectedly.
I disagree with you on what you said above, you are sounding more of a trader than an investor.
