That's true to some extent. However, if you invest huge capital, you can start cashing out without playing the game. In my case, I entered this game with a 300 USD capital at the height of the hype in August 2021. After more than 3 years, I could say that there is no better time to join the game than now. The capital I used then would make me 30x richer now in terms of SPS ownership. As for the value of the cards, it is easier to level them up now than before. Of course, the mechanics of the game isn't easy.
