Lately it seems like cryptocurrency is everywhere. From the now-ubiquitous tales of “Bitcoin millionaires” to the increasing number of companies jumping into the crypto arena, it’s hard to ignore the news—or the feeling that not owning cryptocurrency means missing out. The price of one bitcoin has ranged from $1,000 in early 2017 to more than $66,000 in October 2021—but with intense volatility, including periodic drawdowns of more than 50%, in between.
So what is cryptocurrency? Should you invest in it? How can you invest in it? We’ll cover all three topics in this and related articles. For now, here are answers to some of the most common questions about the basics of Bitcoin and other cryptocurrencies.
What is Bitcoin?
Bitcoin is a virtual, digital, or “crypto” currency—so called because of the cryptography, or unchangeable coding techniques, involved in the blockchain code on which they exist. The intent of Bitcoin is to allow online payments to be made directly from one party to another through a worldwide payment system, without the need for a central third-party intermediary like a bank. Bitcoin is not issued by any central bank or government and is not legal tender (meaning a national currency established by statute) in any country except El Salvador. Like physical gold, Bitcoin’s value stems from a combination of scarcity and the perception that it is a store of value, an anonymous means of payment, or a hedge against inflation.
What’s the relationship between Bitcoin and blockchain?
Blockchain, the underlying technology that supports cryptocurrencies, is an open-source, public record-keeping system operating on a decentralized computer network that records transactions between parties in a verifiable and permanent way. Blockchain provides accountability, as the records are intended to be immutable, which presents potential applications for many businesses. While blockchain has often been associated with cryptocurrencies, it has many potential uses beyond payments, including smart contracts, supply chain management, and financial services. Note that ownership of Bitcoin or other cryptocurrencies is not an investment in blockchain, the technology, or its current or future uses.
What is cryptocurrency, and how is it valued?
Fiat currencies like U.S. dollars and euros are forms of money issued by governments to serve as legal tender. Cryptocurrencies such as Bitcoin, on the other hand, are “non-fiat,” non-governmental forms of “digital cash” to be used for electronic payments. The idea of “digital cash” isn’t new—it started with credit cards, PayPal, Venmo and other services’ need for easy, traceable electronic payments. But those payments are tied to fiat currencies managed by central banks, whereas cryptocurrencies are managed by technology, specifically cryptology. Proponents believe the value of a cryptocurrency is based on the quality of the cryptology, the number of cryptocurrency units created, and the technology that limits the creation of additional units. Like any traded item—think baseball cards—the value depends on supply and demand: The fewer units available, the higher the price buyers are willing to pay.
Why has Bitcoin become popular?
Like many new technologies or products, Bitcoin attracted adherents interested in innovation and the perceived absence of governmental control. Traders saw it as an alternative to traditional investments such as stocks, bonds, and cash, and trading momentum led to a rising, if highly volatile, price. All of this attracted media attention, which drove mainstream awareness and ultimately, increasing acceptance, and a market to trade it. Most recently, companies including PayPal have announced that they’ll support or accept Bitcoin as a form of payment.1
Who oversees Bitcoin?
Bitcoin was created based on a paper written in 2008 by a “founder” who goes by the pseudonym Satoshi Nakamoto, but no person or agency currently regulates it to ensure that it maintains value and liquidity and works as a means of payment. It’s governed by consensus of a private digital community according to guidelines based on the community, cryptology, and a network of computers. While individual countries may allow Bitcoin to be used as a means of payment, regulate the terms under which its citizens can trade or mine Bitcoin, and authorize the operation of cryptocurrency exchanges, they don’t regulate/control the existence or value of Bitcoin itself, or the blockchain code on which it operates. Bitcoin is promoted by the Bitcoin Foundation, but the foundation also does not control or manage Bitcoin’s trading or value. The number of bitcoins in circulation is limited by and managed by computer code and traded through one of several digital, decentralized exchanges.
How many investors own Bitcoin?
No one knows for sure, but according to Bloomberg, as of November 2020, 95% of all Bitcoin was held by only 2% of all account holders.
Is Bitcoin the only cryptocurrency?
No. Bitcoin was the first cryptocurrency and it is the best known, most widely held, and—with about 44% of the total cryptocurrency market cap2—the most valuable. However, as of October 2021 there were thousands of digital currencies in the marketplace, of which more than 100 have a market capitalization exceeding $1 billion. Some of the more popular cryptocurrencies include Bitcoin Cash, Cardano, Tether, Ethereum, Polkadot, and XRP.
In October 2021 Federal Reserve Chair Jerome Powell and SEC Chair Gary Gensler both stated that they didn’t intend to outlaw cryptocurrencies, but Gensler said the SEC was exploring how best to ensure that the industry protects investors and consumers and follows anti-money laundering and tax compliance laws.
China already has launched a digital yuan and it is estimated that at least 80 different countries around the world, including the United States, are exploring the idea of launching their own proprietary Central Bank Digital Currency. While the Fed, the U.S. Treasury and the SEC have been noncommittal on the topic, in October 2021 Powell remarked that “it is more important to do this right than to do it fast.” This implies that it may not be a matter of “if” but rather “when” the U.S. develops its own digital dollar.
Schwab continues to monitor cryptocurrencies as regulations and technology evolve. While some traders have made money on the change in price of Bitcoin or other cryptocurrencies (and others have lost money), we suggest that most investors treat them as a speculative asset primarily for trading with money outside a traditional long-term portfolio.
