These days, a bunch of "sandwich" and "arbitrage" screenshots are flying on the blockchain again. My first reaction isn't opportunity, but: am I just working for others paying fees... Honestly, the price difference you see might have already been snatched up by bots waiting in line. Now I always check the slippage and depth before placing an order; if I can split it up, I do. Better to be slow than to step into someone else's lunch in one go. By the way, the community is also arguing about privacy coins, coin mixing, and the boundaries of compliance. I'm quite conflicted too—want to protect myself but afraid of crossing the line. Anyway, I make sure to keep traces and risk controls in place. As for what I don't regret: I go through new chains and bridges first. If I get caught out, so be it— but the experience really grows quickly.
