PANews reported on September 15 that according to Bloomberg, Hadley Stern, chief business officer of Marinade, a Solana custody tool, said that the custody cost in the crypto field is 10 times that of protecting traditional assets such as securities and cash, making it a potential growth area that attracts startups, Wall Street banks and other companies seeking to enter digital assets. Stern previously worked at Bank of New York Mellon in charge of digital asset custody. So far, crypto-native companies such as Coinbase Global Inc. and BitGo Inc. have been the dominant service providers, while traditional financial companies are mostly in holding mode because of concerns about regulatory uncertainty surrounding digital assets. Although the current custody market size is only about $300 million, the business is still attractive, and companies such as Fireblocks Inc. estimate that the industry is growing at an annual rate of about 30%. Head custody banks BNY Mellon, State Street Corp. and Citigroup Inc. have already made initial forays into cryptocurrency custody or expressed interest.
