Last night I got curious again and checked out a yield aggregator, watching the APY jump around like a pixel cat ECG... Honestly, the returns aren't coming out of nowhere; there's either a contract layer that twists and turns, or the counterparty is lending you money to do other things. The contract is written in a flashy way that I can't understand deeply, but at least I now look at it first: which pool the funds are going into, whether withdrawals are possible, and if permissions can still be changed at any time. Recently, AI agents and automated trading systems have been very popular, with narratives being hyped up, but the more automated the on-chain interactions become, the more I fear "automatic transfer of my money away." So I usually test with small positions—if I make a profit, I withdraw; if I lose, I take it as a lesson. That's the plan for now.
