There is speculation that as more financial institutions invest in bitcoin, more companies will join. Some investors believe that it could be a good hedge against inflation and a weak dollar. The Federal Reserve cut interest rates in March 2020, severely weakening the US dollar and shooting up the price of bitcoin.
So if you've been ignoring bitcoin thinking it might just be a financial fad, now's the time to start paying attention. Here's what you need to know.
Bitcoin is a cryptocurrency created in 2009 by an unknown person using the alias Satoshi Nakamoto. Transactions are anonymous and are made with no brokers or intermediaries.
You can't physically use bitcoin -- it's a digital currency. And it's decentralized, meaning that it isn't controlled by a bank or government.
Bitcoin is 100% digital. Marketplaces called "bitcoin exchanges" allow people to buy or sell bitcoins using different traditional currencies. Coinbase is a leading exchange, along with Coinmama, CEX.IO and Gemini.
Bitcoin is stored in a digital wallet, which is either on the cloud or your computer. It's like having a virtual bank account. But unlike bank accounts, stored bitcoin isn't insured by the FDIC.
Elon Musk, CEO of Tesla and SpaceX, has a history of tweeting support for assets and sending their value soaring, and the world's richest man is very big bitcoin booster.
Not long after that he formalized Tesla's relationship with the crypto, the corporate announcements started flowing.
The cryptocurrency is highly volatile, and therefore very risky. For example, in January bitcoin's value rose to $42,000, fell to $30,000, then rose again to $40,000 -- all in the course of one week.
And there some inherent dangers to a digital currency: A hacked server, a deleted file or a lost password could mean the funds are lost forever.
