This article is a continuation of “How One Decision Saved This Trader Thousands”, a true story about a trader who doesn’t just buy low — they trade smart, saving themselves thousands in fees.
Quick recap. In April 2025, with ETH near $1,600, a trader wants to buy the dip. Two paths:
Default DEX (AMM swap): used by most — not because it’s better, but because it’s how early DeFi DEXs were built.Carbon DeFi (maker-style limit order): a DEX experience that puts traders in control, eliminating inherent risks and inefficiencies of the AMM.
They choose Carbon DeFi. A single limit order turns $50,000 USDC → 31.17 ETH with:
Zero slippage & 100% price certaintyZero protocol or trading fees on executionFull immunity to sandwich attacks
After the buy fills, they switch the strategy type to a limit sell at $5,585 USDC/ETH.
Now, four months later, they turn 31.17 ETH → 36.3 ETH in two moves — while avoiding typical AMM taker fees, slippage, and DeFi’s most predatory attacks.
