Recently, I've been seeing everyone talk about "sandwich" and "arbitrage," and many people say they've seen opportunities. My first reaction, however, is: am I just paying extra fees for others again? That feeling of being squeezed on the chain really feels like you just ordered takeout and the platform added a delivery fee, but the bill is all on you.

My current approach is: if I can set a limit order, I do; don't chase slippage, and it's okay if the execution is slower. If I really want to make a trade, I treat it as a lesson learned, don't leverage, and don't stay up all night staring at those two K-lines to ruin your mindset.

By the way, the recent heated debate about privacy coins/mixing coins is basically about "wanting privacy" versus "fearing regulatory crackdowns," and they just don't see eye to eye. The same logic applies in trading: you think you're finding a loophole, but you might just be standing in the most expensive spot within someone else's rules. That's all for now; I plan to go to bed early tonight.
