Why it moved
Crypto Exchanges Rally to Strengthen Security After Binance Heist. Exchange security events can trigger rapid withdrawals, liquidity stress and sentiment shifts across the entire crypto market, touching Bitcoin, Ethereum and any token traded on affected platforms. Historically, major hacks have also accelerated regulatory scrutiny, which can alter operating conditions for the whole sector.
A $6 Billion Crypto Hack Puts Digital-Asset Security Under Fresh Regulatory Scrutiny. Large security breaches in crypto tend to accelerate regulatory scrutiny, which can affect sentiment across digital-asset markets and spill into related stocks such as exchanges and custodians. If state-sponsored attribution is confirmed, it could also draw in national security and foreign-policy dimensions rarely seen in typical crypto regulatory discussions.

Educational takeaway
Centralized exchanges are honeypots for attackers precisely because they pool large amounts of assets in one place — a structural risk that the concept of self-custody and decentralized finance was partly designed to address.

- Leverage
- Controlling a position larger than the money you put down. It magnifies gains and losses by the same factor. Leverage changes the size of mistakes, not the odds of being right.
