It’s April 7, 2025 — ETH sits around $1,600, its lowest since September 2023.
This is a true story about a trader who doesn’t just buy low — they buy right, saving themselves thousands in fees.
$50,000 and Two Options
Option 1 — The “industry standard”
The default DEX experience — used by most, not because it’s better, but because it’s how the first big wave of DeFi DEXs were built.
Swap on a traditional AMM
Pay anywhere between 0.01% to 1% in swap fees
Add another 0.25% in UI fees depending on the interface used
Lose hundreds of dollars before the trade even executes
Face slippage and execution at worse than advertised rate
Risk becoming victim of a sandwich attack
Trade against a single liquidity pool
Option 2 — Carbon DeFi
A reimagined DEX experience that puts traders in control — eliminating the built-in risks and inefficiencies of the old model.
Place a limit order at the current market price
100% Price Certainty
Immune to sandwich attacks
No protocol or trading fees
Full $50,000 working for them from the start
Trade against the entire Ethereum network
They choose Carbon DeFi.
The Order That Changed the Outcome
They set a limit buy order at $1,604.05 and fund it with the full $50,000.
Carbon DeFi’s built-in solver system instantly scans the entire Ethereum network for the best liquidity — not just one pool.
Within just 3 minutes of creating the order, it fills in three parts:
25.17 ETH for $40,385.70
5.3647 ETH for $8,605.34
0.628995 ETH for $1,008.94
Total: 31.17 ETH, all at the exact price they set.
The Next Step
That ETH still sits on Carbon DeFi, now worth $147,159.82 — roughly triple the original investment.
The exit plan mirrors the entry. The trader simply converts the filled buy order into a sell order at $5,585 per ETH.
When it fills, that’s $174,090 — without watching a chart or taking time away from family and friends in the meantime.
An Expensive Lesson in Fees
Swapping $50,000 on a traditional AMM costs hundreds in fees.
Selling 31.17 ETH at $5,585 through the same system runs ~3.5x as much.
That’s thousands of dollars gone — for just two trades.
And that’s before slippage or a sandwich attack takes a cut.
“That could never happen to me.”
Spoiler: it can. It happens every day.
In the past 24 hours on Ethereum alone:
56 attackers execute 2,911 successful transactions
2,315 traders became victims to sandwich attackers.
Over $20,000 in profit is taken directly from other traders
These aren’t rare edge cases. Thousands occur every day, in every market cycle, and they only require one thing from you — to place your trade on a DEX that leaves you exposed.
Carbon DeFi is the only DEX giving you full immunity.

Back to Our Trader
This ETH buy on April 7, 2025, isn’t just profitable because the trader had the conviction to buy the dip — it’s profitable because they were smart about how they did it.
Carbon DeFi vs a Traditional AMM
The Irony
Here’s the irony — Bancor, the inventors of Carbon DeFi, also invented the technology that underpins the constant product AMM.
Now, they’re proving the next big leap in DeFi comes from those who built the first one — recognizing when the standard they created no longer serves traders, and having the conviction to rebuild from the ground up.
The Takeaway
Control isn’t a nice-to-have in trading — it’s the difference between keeping your profits and watching them leak away.
Carbon DeFi is the only DEX offering onchain maker-style limit orders that are completely native to the protocol — with zero third-party dependencies and zero added risk. And that’s just one of it’s exclusive features.
This trader didn’t get lucky. They made the best trade because they chose a superior DEX.
