Isn't this actually mathematically the same as arbitrage? :D

  It's literally, identically arbitrage.

    No, arbitrage is a combination of trades that essentially risk free as they offset each other. This is just regular trading. Every time he swaps a card, he takes the risk that he won't be able to offload the new card.

      Doesn't arbitrage come with slight risk too? The spreads are always fluctuating, and if you don't time it right (in say high-frequency trading) you might not be able to offload whatever you just bought at a good price either.

        Strictly speaking, yes, there are risks associated. But there's still a wide difference between those risks, and speculating on the (not-immediate) future.
