Of course he's talking about investing, I think you know that because that's all we're talking about in these days. Not many people are interested in using bitcoin for payments or as currency anymore, and that's the truth.
Bitcoin has its use cases and practical applications, but when it comes to speculation, trading
there is nothing wrong with calling it a zero-sum game. When someone sells for profit, there will definitely be someone who loses and that is the nature of finance, and bitcoin is also a financial market. No financial market can be profitable for both sellers and buyers, and bitcoin is no exception.
If that were the case, then we can now see a number of countries legalizing Bitcoin as an investment asset and this would no longer be an issue.
When it comes to legal tender, I agree because it's not just about being unattractive there are many things that need to be changed such as regulations.
In any economic system, something is considered a zero-sum game, where there are those who benefit and those who lose.
But in this case, if we simplify it and the pattern is implemented correctly, both buyers and sellers benefit. So I call it a different thing, but it's up to each person to see the correlation based on their own perspective.
If there were no financial markets that could benefit both buyers and sellers, I'm not so sure this sector would have grown so rapidly.
Unless we're talking about the short term, there's little resemblance to a zero-sum relationship because there's no new value creation, which is why I don't attribute a zero-sum relationship to Bitcoin.
