Lately, I've been watching on-chain transactions, and sandwich attacks + arbitrage are really annoying... You think you've found a bargain, but it turns out you're just packing slippage and fees to give away. To be honest, many "opportunities" are signals that others are waiting for you to place an order in advance. Now, I care more about: whether there's enough liquidity, whether withdrawals will get stuck, and whether I'm just acting as a liquidity tax.

My mom also asked me, "Don't you just click once to buy coins, how come you're still getting 'sandwiched'?" I just replied half-jokingly: On-chain is a public queue, and someone cuts in line, using you as toll...

By the way, the privacy coin/mixing debate in the community is also pretty heated. Some say privacy is a right, while others say don't touch the compliance red lines. Anyway, I'm now leaning towards a more conservative strategy: willing to earn less, rather than discovering one day that all my gains are just "others' fees" and I end up getting caught in a trap. That's it for now.
