In 2014, Mt. Gox, once handling over 70% of global Bitcoin trades, suffered a devastating hack - 850,000 BTC vanished. The exchange filed for bankruptcy, leaving thousands of users without their funds.

But what went wrong - and what can we learn?

3 Key Lessons from the Mt. Gox Collapse:

1. Not Your Keys, Not Your Coins

Mt. Gox was a custodial exchange - users didn’t control their private keys. When the platform failed, their coins were gone too.

Takeaway: Use non-custodial wallets for long-term storage.

2. Centralized Exchanges Are Not Risk-Free

Just because a platform is popular doesn’t mean it’s safe. Gox lacked proper audits, security protocols, and transparency.

Takeaway: Choose exchanges with strong security records and consider cold storage for large holdings.

3. Regulation Isn't the Enemy - It's Protection

The collapse pushed governments to start regulating crypto, demanding better protections for users.

Takeaway: Responsible regulation can help prevent future disasters.

Today, Mt. Gox serves as a crypto milestone, reminding us that security, self-custody, and due diligence are non-negotiable in Web3.

Still wondering why people say “Not your keys, not your coins”? This is why.
