Today I saw someone talking about sandwiches and arbitrage again, saying "the opportunity is here."

My first reaction to these two words now is: am I actually just helping others gather fees...
Honestly, you think you're grabbing a piece of meat, but you might just be standing on the cutting board smelling the aroma.
The blockchain is too transparent; details like reaction speed, order priority, and slippage can be exposed with a flick, and in the end, what you pay extra or get less adds up, which can be quite painful.

Recently, the NFT royalty debate has also been intense, with one side saying they want to protect creators, and the other saying that without liquidity in secondary sales, everything dies.
It sounds reasonable, but it’s also quite like that tug-of-war in trading where everyone wants to pay less, but someone still has to buy.

Anyway, before I place an order now, I pause for two seconds and ask myself: is this really my profit, or just someone else’s process cost?
What I’ve learned isn’t skills, but rather to tone down the illusion of “I’ve made money.”
