Yield aggregators that make your eyes blind with APY at a glance, to be honest, I now think in terms of "contracts + counterparties": which pool the money actually went into, where the yield comes from, who has the authority to change parameters, who takes the blame if something goes wrong. I used to impulsively jump in, but later I learned my lesson from a strange contract upgrade; when I lost money, I just turned off the computer and went for a walk… No matter how good the form is, it can't save contract risks.

There’s also social mining, fan tokens, and the “attention as mining” approach. I find it a bit uncomfortable to listen to; attention is indeed valuable, but most of the time it’s more like disguising liquidity risk, everyone rushes to ignite it, and in the end, the emotional sentiment still takes the final seat. Anyway, I now prefer to earn less if I can understand it.
