It is gambling, but if you can justify your odds being higher than mere chance, then it&#x27;s a gamble you want to make ;)<p>I do agree that on a long-term basis it is quite unpredictable if Lego would still appreciate in value. But I guess it would be quite reasonable to make a good guestimate for the next 3 years and popular Lego appreciating in price. I do assume that I&#x27;d be able to research and understand when a Lego model goes out of production.<p>In other words, I believe that the reality is a lot more subtle than &quot;In the end it&#x27;s just gambling.&quot; I don&#x27;t think it&#x27;s <i>just</i> gambling.
