Bitcoin and ethereum prices today, Monday, September 21, 2026: Crypto prices hit highest levels in 8 months

On Monday, September 21, 2026, Bitcoin and Ethereum prices reached their highest levels in eight months. Bitcoin opened at $81,162.18 and surged to a high of $85,134.02, while Ethereum opened at $2,644.80 and increased to $2,713.90. Despite the recent failure of the CLARITY Act, these prices are surging. This surge can be attributed to three main factors: a drop in oil prices, a strong weekly close for Bitcoin, and a surge in short sellers.

Bitcoin and Ethereum are cryptocurrencies that operate without government or banking oversight, using a decentralized blockchain ledger for secure transactions. Both have all-time high values and low values recorded in recent years. Buying Bitcoin can be done through crypto exchanges, fintech apps, or traditional brokerages. It's important to understand that Bitcoin is a high-risk, highly volatile asset, and volatility is part of the deal.
