I just realized I was stupid again: I clearly saw that the pool was quite large when swapping tokens on the chain, but in reality, the depth was thin, and the slippage completely confused me... I'm also impatient, seeing other transactions in line, I hurried to add priority fees to cut in line, but as a result, the price kept chasing me, and I lost my composure at the moment of the trade. After reviewing, it was still a timing issue with placing orders: don't force it during the most volatile few minutes, split into two trades, or wait until the network congestion eases a bit, which is actually more stable. Recently, with the rate cut expectations and discussions about the dollar index heating up, risk assets are moving together—sometimes soaring, sometimes falling together, making on-chain "fake depth" easier to see. Honestly, don't trust the interface at first glance too much. Sigh, really frustrating, let's leave it at that for now.
