Day 202Part 6: Security & Self-Custody

The Celsius Collapse

In June 2022, Celsius Network — one of the largest crypto lending platforms in the world — announced it was pausing all withdrawals, swaps, and transfers.

For approximately 1.7 million customers, this meant their funds were frozen. Immediately. Without warning. The platform had been marketing itself as a safe, high-yield alternative to traditional banking. “Unbank yourself” was their slogan. Customers had deposited billions, attracted by yields of up to 18% on their crypto holdings.

Behind the scenes, Celsius had been making increasingly risky bets with customer funds — investing in illiquid DeFi protocols, making undisclosed loans, and operating in ways that regulators would later describe as a Ponzi scheme. When the broader crypto market fell in 2022, the positions unwound catastrophically.

Celsius filed for bankruptcy in July 2022. The $8 billion in frozen customer funds became the subject of years of legal proceedings. Many customers received partial recoveries — some received nothing.

The people who lost money weren’t reckless. They were attracted by a credible-sounding platform with a slick app, celebrity endorsements, and yields that seemed extraordinary but not impossible. They trusted a centralised custodian with their Bitcoin.

The pattern is identical to Mt. Gox, QuadrigaCX, and FTX. A centralised platform. Customer funds at risk behind the scenes. No warning before the freeze.

The Bitcoin protocol didn’t fail any of these customers. The centralised businesses built around it did.

Tomorrow: the pattern across every exchange failure — what they all had in common.
