Yet, despite the latest escalation in the Middle East, prices for bitcoin and ethereum today are building off a stronger trend we saw last week. Institutional demand for bitcoin ETFs is helping to prop up values. Whether this price rally can continue will certainly depend on whether the interest in bitcoin ETFs is sustained.

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 defends against manipulation attempts.

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.
