Ethereum (ETH) price is down by 2.6% today, September 15, to trade at $2,446 at the time of writing. This drop comes ahead of the Federal Reserve decision on interest rates. CoinGape Prediction markets show that there is an 80% chance that the Fed will hike interest rates by 25 basis points. ETH traders may have already priced in this hike because rising outflows from exchanges suggest an unwillingness to sell in the near term.
