Weakness in cryptocurrencies results when the prevailing sentiment gets more conservative. Investors fearing an extended Middle East conflict that invites inflation and, possibly, recession tend to trim their more volatile assets, including bitcoin and ethereum.

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.
