Staring at the glaring $50 fee on the transaction record, I felt completely numb. This is already the third time this month I've been Clip Coupons on gas fees. Last week, while chatting with my fren, he casually mentioned that swapping stablecoins basically costs nothing, and that's when I realized I've been the sucker all along.

**Every operation is a hidden loss of blood**

The truth that many people don't know: when you swap 10,000 USDT on certain DEXs, the price seems equivalent on the surface, but in reality, the Gas fee eats away 0.3%, the slippage takes another 0.5%, and cross-chain transactions get hit with an additional 0.2%. When you calculate it, for every 10,000 bucks operated, 100 bucks silently evaporates — enough for me to drink milk tea for more than half a month.

I remember one time I was in a hurry to convert 50,000 USDT into USDC for a payment at midnight, but I ran into network congestion, and the Gas fee skyrocketed to 87 dollars, with a slippage of over 2.3%. That single transaction cost me nearly 300 dollars, two days of work wasted. At that moment, I really wanted to smash my computer.

**Unexpectedly Discovered Money-Saving Channel**

One early morning, while scrolling through my phone, I accidentally opened the DyorSwap interface. For the same exchange of 10,000 USDT, the estimated fee displayed was $0.01. I thought I was seeing things and refreshed several times to confirm it wasn't a bug.

This is the charm of the Plasma ecosystem. In this system:
- Transaction confirmation completed in 3 seconds
- Single transaction Gas fee stabilized at 0.00
