Embezzlement

Embezzlement is the theft of assets by a person entrusted to manage them, an insider crime distinct from robbery or hacking. Financial history is punctuated by it, and the crypto era produced one of the largest cases on record: FTX's 2022 collapse, in which roughly 8 billion dollars of customer funds were misappropriated, ended with founder Sam Bankman-Fried sentenced to 25 years in prison.

Why it matters

Embezzlement is the purest form of counterparty risk because it defeats every protection except not trusting the counterparty in the first place. Audits, regulation, and reputation all failed at FTX, at MF Global in 2011, and in countless bank and brokerage scandals before them. The perpetrator holds the keys legitimately, so no vault or firewall stands in the way.

The crime shapes financial architecture. Segregation of customer funds, third-party custody, proof of reserves, and multi-signature controls all exist because history shows that some fraction of trusted insiders will steal, given opportunity and time.

In the gold vs bitcoin debate

Both assets are vulnerable the same way, through custodians, and protected the same way, through direct possession. Vaulted gold and exchange-held bitcoin each depend on someone else's honesty, while metal in hand and keys in self-custody remove the trusted insider entirely. Bitcoin adds one novel defense: reserves at an address can be proven cryptographically to anyone, whereas verifying vault gold requires physically counting bars.
