These days, I’ve seen people talk about sandwiches and arbitrage again, calling it a "chance." My first reaction is: am I standing on someone else’s menu... You think you're saving on fees, but you're actually paying tuition to the faster guys. On-chain, it looks very fair, but in reality, whoever is faster and understands routing better can eat up your slippage completely.

NFT royalties are also quite a heated topic: creators want income, the market wants liquidity, and in the end, many times, ordinary people just get a layer of skin peeled off through buying and selling. Honestly, the more lively the secondary market, the more tricks there are with fees.

I need to be reminded: before taking action, check the transaction path, look at the pool depth, don’t rush in impulsively, be restrained, and don’t see yourself as “liquidity” itself.
