KOL @Cbb0fe returned to the public eye for alerting early about the risks of Stream Finance. His journey is quite the story; despite facing constant controversies along the way, he remains a legendary figure in the blockchain world from nothing to something. Recently, he wrote on his personal Twitter, "How we earned over $50 million by sniping junk coins on decentralized exchanges," detailing CBB's experiences in the crypto space over the past five years.
The Legendary Beginning: French Brothers Starting with $40,000
In the summer of 2020, as the world remained shrouded in the shadow of the pandemic, two French brothers faced a career turning point. The older brother was a professor of 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 downturn, and their investment portfolio was back to around $50,000, thanks only to a few wins on Binance Launchpad.
It was at this time that they heard a new name: Uniswap.
Several friends made profits from meme coins on this decentralized exchange (DEX), earning three to four times in just a few hours. One story particularly shocked them: a robot made $500,000 using sniping techniques when the bZx token launched. The brothers were stunned and decided to try to understand this new technology.
Started self-learning to develop a token sniping bot on Uniswap.
CBB learned Solidity during a family trip and developed a token sniping bot himself. The first target was $YMPL. They raised 50 ETH (about 20,000 USD), secured 8% of the supply, and sold within 30 minutes, netting 60 ETH. A few days later, they battled $VIDYA, investing 165 ETH and earning back 159 ETH in 15 minutes. Next was $CHARTEX, with a single profit of up to 135,000 USD. In just two weeks, their assets multiplied.
To act faster, they delved into the workings of Uniswap. When a team launched a token, they had to submit an 'Add Liquidity' transaction on-chain. Ordinary people waited for transactions to be on-chain before buying, always lagging by one block. They discovered that by running their own Ethereum nodes, they could monitor the mempool (transaction memory pool) and detect liquidity addition signals before transactions were packaged, allowing them to place orders immediately and enter the market first. This breakthrough enabled them to enter a world on par with professional block hunters.
In September of that year, they faced a life-changing battle: $CHADS. In just one hour, they made a profit of 675 ETH (about 270,000 USD) from 200 ETH. In the following days, they made a killing on tokens like $FRONTIER, $LINA, and $CHARTEX, earning 2300 ETH. In the same month, Uniswap airdropped UNI tokens, and the brothers suddenly gained hundreds of thousands of dollars overnight from their hundreds of test wallets.
Running Ethereum nodes, they resigned from their university teaching jobs and moved to Dubai to trade.
Entering October, they completely standardized their processes. The younger brother developed a dynamic order placement mechanism that could automatically adjust purchase limits based on each ETH, allowing for real-time execution regardless of whether the liquidity pool used ETH, USDT, or USDC. They then discovered that speed was critical based on geographical location. They set up multiple Ethereum nodes to compete against each other, and the results showed that the node located in AWS North Virginia was faster than those in other regions.
The reason is that the Infura RPC nodes used by MetaMask were primarily located there at that time. So they moved all their servers to this location, minimizing latency.
In December, Polkastarter rose. 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, netting a profit of $500,000.
This event made the brother determined to resign from his teaching job and fully invest in token sniping. 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 USD.
Transitioning from Ethereum to BSC, their monthly income exceeded 100 million.
As token sniping behavior became rampant, project teams began to take countermeasures: purchase limits, wallet restrictions, and delay mechanisms. The younger brother continued to innovate countermeasures.
Loop buy contract: automatically placing multiple orders in a single transaction to bypass single order limits;
Multi-wallet slave contracts: the main contract calls dozens of sub-contracts to buy simultaneously, bypassing wallet limits.
These innovations allowed them to continue winning battles during the Polkastarter craze in early 2021.
In February 2021, they noticed the explosive growth of BSC (Binance Smart Chain). Buying BNB at $80, they made a net profit of 800 BNB in the first $BRY token sniping. They then invested 75 BNB in $MATTER, gaining 2100 BNB. In March, their monthly income reached 15,000 BNB (worth over 4 million USD at the time), with a single profit of 8300 BNB from $KPAD, setting a personal record.
At the peak, they had 150-200 AWS nodes, dominating BSC with just two people.
To improve hit rates, they established a distributed infrastructure: 150–200 AWS nodes monitoring transactions globally, with each node sending 10 transactions. The monthly cloud costs reached 40,000–60,000 USD. 'We have no employees, no outside help, just two people,' CBB wrote. But this cost also created a barrier, allowing them to dominate BSC.
In May, they made 3 million USD arbitraging from 120 wallets with $PINKM (Pinkmoon). The next day, the older brother drove his newly purchased Lamborghini Aventador SV on the street. However, the craze quickly faded, and the crypto market cooled after June. They liquidated their BNB holdings and chose to take a break. While cleaning their old wallets, they found that the previously blacklisted $EVN token had been unlocked. In just fifteen minutes, they sold off all their wallets, unexpectedly cashing out 6 million USD. In the same month, they also liquidated their main holdings when ETH reached 3000 USD, achieving financial freedom.
The two brothers started with 40,000 USD and achieved financial freedom.
In just one year, the two brothers went from having only 40,000 USD to sweeping over 10 chains and more than 200 tokens with their token sniping bot, accumulating over 50 million USD in profits. They were not early engineers nor did they have a venture capital background; they carved a path as on-chain hunters solely based on their understanding of mechanisms and obsession with speed.
CBB wrote at the end: 'That year felt like a dream that could never be replicated. The pressures and thrills we experienced are hard to put into words. I wish everyone could find their own journey.'
