Recently, I've been looking at that pile of "sandwich + arbitrage" on the chain, and honestly, you think you've found an opportunity, but often you're just helping others pay transaction fees... I myself keep an eye on the mempool and block packing order, but the more I watch, the more I feel: ordinary people manually clicking a swap, turning on slippage, is basically just sending red envelopes to bots. What's more annoying is that sometimes it's not even your wrong judgment—it's a wallet signature delay or RPC hiccup, misestimating gas and getting caught in the middle, making you want to smash your keyboard.

The inflation + studio + coin price spiral in blockchain games also seems to follow this logic: watching someone "make money," but actually it's just shifting system friction and selling pressure outward, ending up with a mess.

What I don't regret is... asking myself first, "Am I just providing liquidity/fees?" before deciding whether to go all in, at least to avoid being educated as a leek (newbie). That's all for now.
