Recently, someone on the blockchain has been talking about sandwiches and arbitrage, calling it a "chance."

I am increasingly convinced that the small price differences retail investors see are often just the transaction fees that others have already queued up to collect;
if you rush in, you're just working for liquidity providers and MEV...
In other words, you think you're picking up money, but you might just be increasing transaction volume for others.

And now, many on-chain data tools and address labels are also criticized for being outdated or misleading;
seeing some "smart money" follow a trade and feeling reassured?
I personally don't trust that much—by the time you see it, it's usually already the second half.
I'd rather go slower, take more time to see what the protocol actually earns from, where the fees come from,
at least then I know what I'm losing.
What about you?
