I started recording every moment when I felt "this trade has arbitrage potential," only to realize that most of the time what I see isn't actually an opportunity, but rather someone has already lined up to make me pay the transaction fee... Especially on-chain, where the slippage skyrockets right after confirmation, and when I look at the transaction order later, hmm, the sandwich attack flavor is too strong.

Even more outrageous is when I come across a bunch of analyses that combine ETF capital flows, US stock risk appetite, and then force-fit it into an interpretation that "cryptos should rise/fall," and I get emotionally triggered to chase. But then, when the funding rate changes or positions get squeezed, I become part of the liquidity. The point of recording now is to make me pause for two more seconds before opening a position, to trade lightly, and not always be the "fee item" in someone else's profit and loss statement.
