Most people assume that crypto sitting in an exchange account is theirs the same way cash in a bank account is theirs. It isn’t, and the difference matters most exactly when you can least afford to find out the hard way.
What commingled custody actually means
When you deposit crypto into a typical exchange account, it usually goes into a shared pool along with everyone else’s deposits. You hold a claim against the exchange, not a segregated, identifiable asset with your name on it. If that exchange goes bankrupt, you’re an unsecured creditor standing in line with every other account holder, hoping the estate has enough left to make people close to whole. That’s not custody in the way most people picture it. It’s exposure to the exchange’s balance sheet.
The alternative: FBO accounts
An FBO account (For Benefit Of) is structured differently. It’s a separate account held in your name, with your assets kept apart from the platform’s own holdings and from other clients’ assets. If the custodian fails, assets held this way are legally yours, not part of the company’s estate available to creditors. The SEC’s custody rules for investment advisers exist precisely to draw this line between client assets and firm assets.
Why segregation matters beyond bankruptcy protection
Segregated custody isn’t only about what happens if a platform fails. It also changes what you can do with the assets while things are going fine. Once counterparty risk is off the table, a custodian can build institutional-grade strategies around those assets, real yield generation with actual risk controls, rather than the retail options most exchange accounts limit you to.
The question worth asking your platform
The mental model is simple: commingled custody functions like a claim on a shared pool, similar to depositing at a bank that can use your funds for its own purposes. FBO custody functions more like a brokerage account, where the assets in your name stay yours regardless of what happens to the firm. Before you decide where serious money in crypto belongs, ask the platform directly: is my account segregated, or is it commingled with everyone else’s? If they can’t answer clearly, that’s your answer.
