Bitcoin just fell under $79,000 — $40 billion in market cap wiped out in one hour.

This is what volatility looks like in real time. When $BTC moves fast, leverage gets crushed and positions unwind in cascades. The speed matters more than the number sometimes.

Two things to watch:

1. Where support actually holds — $79k breaking changes the technical picture, and the next meaningful level could be $75k-$76k if selling accelerates

2. Whether this is a liquidity flush or the start of something bigger — macro backdrop (rates, dollar strength, risk-off sentiment) will tell you if this bounce back or continues bleeding

Sharp drops like this often shake out weak hands and overleveraged traders. If you're long-term focused, these moments separate noise from signal. If you're trading, this is where risk management either saves you or destroys you.
