These days, the network is congested again, and I just remembered the thing called mempool:

Your transaction is actually queued first, and miners/validators pick which one to include based on who offers the better fee.
You think that once you click confirm, it's done, but in reality, it might get stuck for half a day, get front-run by others, or even fail in the end, and you still have to pay some "tuition" (gas fees may not be fully refunded).
Slippage also changes accordingly, and it’s pretty easy to get frustrated.

What I fear most is not losing money, but losing control—thinking you're just swapping tokens or adding to a position, but it turns into “Will it execute at all? At what price?”
That feeling is even more uncomfortable than losing a bit of money.

Recently, everyone is comparing on-chain yield products with RWA and US bond yields.
I can understand the desire for certainty, but these small hiccups like network congestion just remind me:
Earning steady fees is pretty sweet, and don’t get yourself into a situation where you’re gambling on luck in the mempool every time.
That’s all for now.
