How can Crypto Assets achieve financial freedom on-chain? An in-depth look at the pro CBB's rise to success.

KOL @Cbb0fe has returned to the public eye due to his early warning about the risks of Stream Finance. His experience is quite storied; despite the controversies along the way, he remains an on-chain legend who built himself from scratch. Recently, he wrote on his personal Twitter, “How we made over 50 million dollars by sniping junk coins on decentralized exchanges,” detailing CBB's experiences in the crypto world over the past five years.

The legendary beginning: French brothers starting with 40,000 dollars

In the summer of 2020, the world was still shrouded in the shadow of the pandemic, and two French brothers were facing a career turning point. The older brother was teaching computer engineering at a university, while the younger brother (CBB) had just finished a contract as a product manager at an insurance company. At that time, the crypto market was experiencing a prolonged slump, and relying only on a few wins from Binance Launchpad brought their investment portfolio back to around $50,000.

At this moment, they heard a new name: Uniswap.

Several friends are trading meme coins on this decentralized exchange (DEX), and they can earn three to four times their investment in just a few hours. One story particularly shocked them: a certain bot made $500,000 using the sniping method (sniping) when the bZx token was launched. The brothers were utterly astonished and decided to try to understand this new technology.

CBB learned Solidity during a family trip and developed a coin grabbing robot by himself. The first target was $YMPL. They raised 50 ETH (, about 20,000 USD ), grabbed 8% of the supply, and sold it within 30 minutes, netting 60 ETH. A few days later, they went for $VIDYA, investing 165 ETH and earning back 159 ETH within 15 minutes. Next was $CHARTEX, with a single profit of up to 135,000 USD. In just two weeks, their assets multiplied several times.

To act faster, they delved into the workings of Uniswap. The team must submit an “Add Liquidity” transaction on-chain when listing a coin. Ordinary people can only buy after the transaction is on-chain, always a block behind. They discovered that by running their own Ethereum node, they could monitor the mempool (transaction memory pool) and detect liquidity addition signals before the transaction is packed, allowing them to place orders immediately to get ahead. This breakthrough has allowed them to enter a world on par with professional block hunters.

In September of that year, they welcomed the battle that would change their fate: $CHADS. In just one hour, they earned a profit of 675 ETH (about $270,000) from 200 ETH. In the following days, they made a wild profit of 2300 ETH on coins such as $FRONTIER, $LINA, and $CHARTEX . In the same month, Uniswap airdropped UNI tokens, and the two brothers saw their hundreds of test wallets suddenly gain hundreds of thousands of dollars overnight.

Entering October, they thoroughly standardized the process. The brother developed a dynamic order placement mechanism that can automatically adjust the purchase limit based on each ETH, allowing for instant execution regardless of whether the liquidity pool uses ETH, USDT, or USDC. Later, they discovered that speed is key to geographic location. They set up multiple Ethereum nodes to compete with each other, and the results showed that the node located in AWS North Virginia (North Virginia) was faster than those in other regions.

The reason is that the Infura RPC nodes used by MetaMask at that time were mainly located there. Therefore, they relocated all the servers to this location, minimizing the latency to the limit.

In December, Polkastarter emerged. The first project, SpiderDAO, set a limit of 2.5 ETH per wallet, but they found that the restriction only existed in the front-end UI. By interacting directly with the contract, they bought half of the shares, making a profit of 500,000 USD in a single round.

This incident made my brother determined to resign from his teaching position and fully devote himself to grabbing coins. In January 2021, they moved to Dubai. At that time, Ethereum rose from $200 to $1400. In just five months, their earnings exceeded $3 million.

From Ethereum to BSC, monthly income exceeds 100 million.

As the behavior of hoarding coins becomes rampant, project teams have begun to take countermeasures: purchase limits, wallet restrictions, and delay mechanisms. The younger brother continues to innovate countermeasures:

Loop Buy Contract (: Automatically place multiple orders in a single transaction, bypassing single order limits;

Multi-wallet subordinate contracts )slave contracts(: The main contract calls dozens of sub-contracts to buy simultaneously, bypassing the wallet limit.

These innovations allowed them to continue winning repeatedly during the Polkastarter frenzy in early 2021.

In February 2021, they noticed the explosive growth of BSC ) Binance Smart Chain (. Buying BNB at 80 USD, they made a net profit of 800 BNB from the first ) coin grab. Then they invested 75 BNB in $BRY , earning a profit of 2100 BNB. In March, their monthly income reached 15,000 BNB (worth over 4 million USD at the time), including a single session profit of 8300 BNB, setting a personal record.

At its peak, 150~200 AWS nodes dominated BSC with just two people.

To improve the hit rate, they established a distributed infrastructure: 150–200 AWS nodes worldwide simultaneously monitor transactions, with each node sending 10 transactions. The monthly cloud cost reaches as high as $40,000–$60,000. “We have no employees, no external assistance, just two people,” wrote CBB. However, this cost also created a barrier, allowing them to dominate on BSC.

In May, they made a profit of 3 million dollars from 120 wallets using $PINKM (Pinkmoon). The next day, the brother drove his newly purchased Lamborghini Aventador SV out on the street. However, the hype quickly faded, and after June, the crypto world turned cold. They liquidated their BNB and chose to take a break. While cleaning out old wallets, they discovered that the token $MATTER , which had previously been blacklisted, was unexpectedly unlocked. In just fifteen minutes, they sold off all the wallets, unexpectedly cashing out 6 million dollars. In the same month, they also liquidated their main holdings when ETH reached 3000 dollars, achieving financial freedom.

Two brothers started with $40,000 and achieved financial freedom.

In just one year, the two brothers went from starting with only 40,000 USD to sweeping over 10 chains and more than 200 tokens with their coin-snatching robots, accumulating over 50 million USD in profits. They are neither early engineers nor do they have a venture capital background; they have carved out a path as on-chain hunters solely based on their understanding of mechanisms and their obsession with speed.

CBB concluded by saying: “That year was like a dream that can never be replicated. The pressure and excitement we experienced are hard to describe in words. I wish everyone can find their own journey.”
