Bitcoin and other cryptocurrencies have captured the attention of investors, financial institutions, regulators, and media worldwide. The surge in their prices has sparked immense curiosity, yet grasping the fundamental concepts behind these digital assets remains challenging for many.
Several factors contribute to this complexity. Cryptocurrencies often involve technical jargon, especially when delving into their underlying software mechanics. Many are experimental open-source projects where developers, miners, and early investors frequently disagree on project directions. Early investors, who often hold significant stakes, can exert considerable influence. Moreover, cryptocurrencies challenge traditional notions of money, with opinions ranging from heralding them as the future of currency to dismissing them as scams or Ponzi schemes.
This guide introduces the basics of Bitcoin and cryptocurrencies, explores their uses, and discusses key risks to consider before investing in crypto-related stocks or ETFs.
Understanding Cryptocurrencies and Blockchain
Cryptocurrencies, also referred to as tokens, are digital currencies secured by cryptography—the practice of encrypting and decrypting information. Most rely on blockchain technology, a decentralized and distributed ledger that records all transactions. This ledger is virtually tamper-proof unless a single entity controls over 50% of the network's computing power.
Unlike traditional currencies, cryptocurrencies are not controlled by any central authority. For some, like Bitcoin, Monero, and Litecoin, new coins enter circulation through "mining." This process involves computers (mining nodes) competing to solve complex mathematical equations to validate transactions and secure the network. The first miner to solve the equation and create a new block is rewarded with bitcoin, which is then broadcast to other nodes and added to the blockchain.
Other cryptocurrencies use "pre-mining," where coins are mined before public release. Pre-mined cryptocurrencies sometimes face skepticism, as projects may aggressively promote demand to inflate prices, allowing developers to cash out.
As open-source projects, cryptocurrencies evolve as developers address ongoing challenges like scalability and security.
Bitcoin is the largest cryptocurrency by market capitalization. As of a recent tracking, it accounted for a significant portion of the total cryptocurrency market value, which includes thousands of alternative coins.
According to its whitepaper, Bitcoin's creator, Satoshi Nakamoto, aimed to establish a "peer-to-peer electronic cash system." The true identity of Nakamoto remains unknown, adding to the mystery. Estimates suggest Nakamoto holds about one million bitcoin, worth billions at current prices, with minimal movement of these holdings.
A key innovation of Bitcoin is its elimination of trusted third parties for electronic payments, relying instead on network consensus. It created a currency whose supply cannot be altered by central banks or governments. While this may seem less critical in stable economies, it is vital in countries like Zimbabwe and Venezuela, which have suffered hyperinflation due to corruption and excessive money printing.
Different cryptocurrencies offer varied features and purposes. Some were developed to address perceived flaws in Bitcoin or provide additional functionalities. For instance, Bitcoin is not fully anonymous; transactions are publicly traceable on its ledger. Other cryptocurrencies focus on enhancing user privacy.
How Are Bitcoin and Cryptocurrencies Used?
Some merchants accept Bitcoin and other cryptocurrencies directly for payments. Despite high nominal values, cryptocurrencies are divisible into very small units. Bitcoin, for example, can be divided into "satoshis," each worth 0.00000001 bitcoin.
Bitcoin ATMs allow users to buy and sell bitcoin using fiat currencies like USD. Additionally, bitcoin debit cards enable spending by converting cryptocurrency to dollars, functioning like traditional debit cards.
Other cryptocurrencies serve specific purposes. Ether, for example, is used to deploy smart contracts on the Ethereum network.

Cryptocurrency Stocks, ETFs, and Other Products
While direct purchase of cryptocurrencies on regulated exchanges is limited, investors can gain exposure through related assets. However, these investments are high-risk, and crypto-related aspects may only constitute a small part of a company's business.
One approach is investing in companies producing mining hardware, such as semiconductor firms NVIDIA (NVDA) and Advanced Micro Devices (AMD). Some companies, like Microsoft (MSFT) and Overstock.com (OSTK), accept bitcoin as payment. E-commerce platform Shopify (SHOP) also allows merchants to accept bitcoin. Square (SQ) has enabled limited bitcoin trading via its Cash App.
Several U.S. fund companies have filed for bitcoin ETFs with the SEC, but none have been approved yet. The Grayscale Bitcoin Trust (GBTC), an open-ended trust, has traded at high premiums to its net asset value and carries significant risks.
For high-risk-tolerant traders, the CBOE and CME offer bitcoin futures contracts.
Risks to Consider Before Investing
First and foremost, these are experimental products with short trading histories. Investing in crypto-related stocks or potential ETFs carries a high risk of loss.
Although governments may not directly regulate cryptocurrencies, they can regulate exchanges and wallet providers, potentially increasing usage difficulty. Such regulations could alter supply-demand dynamics and limit utility.
Consider your personal risk tolerance and how you've handled volatile investments in the past. Cryptocurrency prices are extremely volatile, and related securities may experience similar fluctuations. If you cannot withstand double-digit percentage swings, avoid these products.
Remember, it's okay to wait until the market matures. Don't let fear of missing out drive excessive risk-taking or emotional decisions. Thorough research is essential given the unique nature of these assets.
