Firstly, despite Bitcoin's distinctiveness and its own complexity compared to other financial forms like fiat currency, gold, etc., its essence remains "money."
Secondly, the price volatility of Bitcoin is highly enticing; it constantly alters our psychology, which is why I refer to Bitcoin as a financial game.
You are right in a way but this can't be entirely right because Bitcoin can do what fiat currencies can do, so if everything surrounding Bitcoin is a financial game, then everything about fiat currencies is as well. But this is not true in reality, it is only some certain aspect they are using them for that can attest to that. Take the buying and selling of your Bitcoin and the use of it to pay and receive money as an example, these are not jokes, no games here.
Personally, they've helped me better in overcoming the cheating and the barrier in cross-border payment. But still, when it comes to staking, trading, investment etc, yes, one may say they are financial games. Coincidentally, I thought of this a few minutes ago before I read your thread that trading is a financial game and the good player earns so much through it. Not knowing that I would still come across something like that today.
Conclusively, anything about the financial market is an indirect game that we need to play technically and intelligently, so you are right halfway.
