The assets recovered by BitGo are now locked in South Dakota in what is known as “cold storage,” which means they're cryptocurrencies stored on hard drives not connected to the internet. BitGo provides what is known as “qualified custodian” services under South Dakota law. It's basically the crypto equivalent of financial fiduciary, offering segregated accounts and other security services to lock down digital assets.
Several crypto companies have failed this year a s bitcoin and other digital currencies have collapsed in value. FTX failed when it experienced the crypto equivalent of a bank run, and early investigations have found that FTX employees intermingled assets held for customers with assets they were investing.
"Trading, financing, and custody need to be different," Belshe said.
The assets recovered include not only bitcoin and ethereum, but also a collection of minor cryptocurrencies that vary in popularity and value, such as the shiba inu coin.
California-based BitGo has a history of recovering and securing assets. The company was tasked with securing assets after the cryptocurrency exchange Mt. Gox failed in 2014. It is also the custodian for the assets held by the government of El Salvador as part of that country's experiment in using bitcoin as legal tender.
FTX is paying Bitgo a $5 million retainer and $100,000 a month for its services.
