As reported by CoinDesk, over the past week the hacker has gradually converted the stolen FTX funds into Ethereum, resulting in approximately $74 million in Ethereum being transferred to BTC using RenBridge, writes Business Insider.

A week ago, the hacker amassed about $288 million in Ethereum¬†after the collapse of Sam Bankman Fried’s cryptocurrency exchange, making him the 35th largest holder of Ethereum in the world.

Analytics firm Elliptic estimates that a total of about $477 million was stolen as a result of the FTX collapse.

However, according to data from Etherscan, the hacker’s Ethereum holdings fell 26% over the weekend.

Elliptic co-founder Tom Robinson said the hackers converted Ethereum into Bitcoin using a blockchain bridge product called RenBTC. Approximately $74 million has been transferred into BTC so far.

That said, Alameda Research, Bankman Fried’s cryptocurrency trading firm and subsidiary of FTX, last year acquired RenBridge, which owns the RenBTC instrument.
