Bitcoin (BTC-USD) opened at $62,829.64 on Monday, August 17, 2026, 0.3% lower than Sunday's opening price. As of 9:17 a.m. ET this morning, the price of bitcoin moved up to $63,413.32.
Ethereum (ETH-USD) opened at $1,874.10 on Monday, August 17, 2026, down 0.4% from Sunday's opening price. The price of ethereum moved higher this morning to $1,894.98 as of 9:17 a.m. ET.
Bitcoin is down more than 3% over the past week, while ethereum has fallen 1.8%. Investors continue to parse conflicting data. Softer economic signals reported last week lower the short-term risk of higher interest rates, and that could support demand for riskier assets. But this crypto bear market has extended long enough to keep investors and analysts guessing. At least one analyst — Adam Livingston — points to Bitcoin's low volatility in recent weeks as a breakout signal, while others see the digital currency falling further before bottoming out.

How Bitcoin works
Bitcoin is a type of cryptocurrency, which is a currency that exists only in digital form and operates without government or banking oversight. By comparison, the U.S. dollar, the EU euro, the Canadian dollar, and other national currencies have paper versions and are issued by their respective governments.
Bitcoin relies on a public digital ledger that validates and records transactions and verifies bitcoin ownership. This ledger is called the blockchain, and it is globally distributed — that is, decentralized — across a broad, worldwide network of servers.
Decentralization is a fundamental aspect of cryptocurrencies. Decentralization facilitates peer-to-peer payments with no banking intermediary, enhanced security, and defense against manipulation attempts.

How to buy Bitcoin in 2026
There are several ways to buy Bitcoin. You can go through a crypto exchange, a fintech app, or a traditional brokerage that will allow you to buy into a bitcoin ETF.
Before placing a trade, though, decide what you actually want: full ownership of your bitcoin and private keys — or easy price exposure inside a familiar, regulated system.
Whichever avenue you take, it's important to remember that bitcoin remains a high-risk, highly volatile asset compared to many other investments. Prices can surge or drop quickly, sometimes without warning. If you're considering buying bitcoin, assume volatility is part of the deal.
