Actually, everyone understands that on-chain, when you think you've found a "risk-free arbitrage," many times you're just helping others gather transaction fees + sandwich attack profits... I was still itching to make a few trades last night, increased the slippage, and the transactions went faster, but when I looked back, the execution price seemed to be pulled by someone by the collar, hilarious, I didn't see any profit, but the gas fees were paid very punctually.

Recently, the incentive programs and points systems on testnets have become popular again, and people are asking in the group every day, "Will the mainnet issue tokens?" In plain terms, as soon as this expectation arises, the network gets even more congested, arbitrage bots become more active, and your opportunities turn into their KPIs. My current approach is very cautious: first, I compare the TVL of similar protocols in a small table to gauge popularity; if the popularity is too high, I avoid them, preferring to miss out rather than become someone else's fee source. That's the plan for now.
