On March 28, online detective ZachXBT issued an article on the official channel saying that I suspect that a Coinbase user was cheated of US$34.9 million (400.099BTC) yesterday. After discovering this scam, I noticed that there were multiple incidents in which suspected Coinbase users had been scammed in the past two weeks. Each time the stolen funds are cross-linked from Bitcoin to Ethereum through Thorchain/Chainflip and exchanged for DAI. Although the fraudulent addresses appeared in the funds of multiple victims, Coinbase did not flag the addresses in its compliance tools.
