Recently, people keep saying that there are "arbitrage opportunities" all over the blockchain, but to me, it looks more like paying tolls for others... Especially those sandwich attacks, I just want to exchange some coins, but the transaction price feels like it was pulled by someone, and when I look back, the slippage plus fees wipe out everything. I really can't see where the opportunity is.

Anyway, the only two things I can do now are: small-scale testing and keeping track of every transaction, and if I lose money, just take it as a lesson learned. Honestly, only a few can outrun the bots; most people are just providing liquidity and paying their dues.

By the way, the economic collapse of those blockchain games is pretty similar: inflation kicks in, studios jump in, coin prices spiral, and in the end, ordinary players are left with only a sense of participation. The same goes for the blockchain—what you see as price differences might just be others' source of fees... That's all for now, being cautious never hurts.
