Actually Safe?

The FTX Lesson: What Went Wrong

In November 2022, FTX — at the time the world's second-largest crypto exchange — collapsed virtually overnight. Around $8 billion in user funds were lost. Founder Sam Bankman-Fried was convicted of fraud and sentenced to 25 years in prison.

What makes the FTX collapse particularly painful is that it was completely avoidable with basic due diligence. The warning signs were there:

• FTX never published Proof of Reserves
• FTX had no independent board or meaningful oversight
• FTX was registered in the Bahamas — a jurisdiction with minimal oversight
• FTX's balance sheet, when finally revealed, showed massive reliance on its own illiquid FTT token

The lesson isn't that crypto exchanges are inherently dangerous — it's that not all exchanges are equal, and a few basic checks can separate the trustworthy from the dangerous.

What is Proof of Reserves?

Proof of Reserves (PoR) is a cryptographic audit that proves an exchange actually holds the assets it claims to hold on behalf of users. Without PoR, you're taking the exchange's word for it — exactly what FTX users did.

Here's how it works:

1. The exchange takes a snapshot of all user balances
2. These are hashed into a Merkle tree — a cryptographic structure that allows individual verification without exposing all user data
3. An independent auditor verifies that the exchange's on-chain wallets hold at least the total of all user balances
4. Individual users can verify their own balance is included using their account hash

The key metric is the reserve ratio — a ratio above 100% means the exchange holds more than users have deposited. A ratio below 100% is a critical red flag.

Where to check Proof of Reserves:

• Binance: binance.com/en/proof-of-reserves — uses Merkle trees + zk-SNARKs
• Kraken: kraken.com/proof-of-reserves — quarterly audits
• OKX: okx.com/proof-of-reserves — monthly updates
• Bybit: bybit.com/en/proof-of-reserves
• Coinbase: Published via SEC filings as a publicly listed company (COIN)

Insurance & Protection Funds

Even with perfect security, exchanges can be hacked. Protection funds exist to compensate users when this happens. Here's what the major exchanges offer:

Binance's SAFU is the most transparent and largest dedicated protection fund in the industry. In February 2026, Binance completed the conversion of its entire SAFU fund into 15,000 BTC, valued at approximately $1 billion, and pledged to rebalance if the value drops below $800 million.

Every major exchange has faced security incidents. What matters is not whether they were hacked — it's whether users were made whole.

Red Flags to Watch For

Before depositing on any exchange, watch for these warning signs:

• No Proof of Reserves — if an exchange won't publish PoR, ask why. There's no legitimate reason not to.
• Registered in a tax haven — Bahamas, Seychelles, or other jurisdictions with minimal financial oversight are yellow flags. Not disqualifying, but worth noting.
• Own token as primary reserve asset — FTX's balance sheet was full of its own FTT token. If a fund is primarily backed by the exchange's own coin, that's a problem.
• Withdrawal delays or limits — legitimate exchanges process withdrawals quickly. Unexplained delays can signal liquidity problems.
• No regulatory licence in your jurisdiction — especially important for EU users under MiCA.
• Unrealistically high yields — if an exchange is offering 20%+ APY on stablecoins, ask where that yield comes from.
• CEO or founders are anonymous — not disqualifying (Satoshi was anonymous), but adds risk.
