A major reason is institutional demand: U.S. spot Bitcoin ETFs recorded approximately $998.95 million of net inflows in one day, the largest daily inflow since October 2025. �

2. BTC is now near an important resistance area
Bitcoin is approaching the $87,000–$90,000 zone. Reports identify around $90,000 as a major resistance area.
The Wall Street Journal
That means volatility can increase if BTC continues moving toward that area.
3. Ethereum is also moving
ETH is trading around $2,740–$2,750 today. It is close to the $2,800 area that traders are watching.

📅 Tomorrow — Sept. 24
There isn't a single confirmed event tomorrow that guarantees BTC will rise or fall. The important thing is that markets are moving into a major derivatives event on Friday, Sept. 25.
Friday's huge options expiry
Approximately $16 billion of Bitcoin options are scheduled to expire on Sept. 25 at 08:00 UTC. Calls represent about $9.6B and puts about $6.4B.
CryptoRank
BTC and ETH options together have roughly $18.1 billion in notional value heading toward the quarterly expiry.

This can mean higher volatility around Thursday–Friday, particularly if traders adjust leveraged positions.
🌎 U.S. economic data
Economic data and Federal Reserve expectations remain important for crypto. The economic calendar shows releases around Sept. 24, so traders will be watching U.S. rates, Treasury yields and the dollar.

🧠 Simple explanation
Money is flowing back into Bitcoin ETFs → BTC rallies → altcoins start moving → traders become more active → the large Sept. 25 options expiry approaches → volatility could increase.
So the biggest story right now is Bitcoin's sharp recovery + nearly $1 billion ETF inflow + the upcoming large options expiry
