There is no single "best" cryptocurrency to invest in, because the right choice depends on your risk tolerance, time horizon, and what you are trying to achieve
Cryptocurrency markets move fast and unpredictably. Bitcoin has the longest track record and largest market value, but newer coins like Ethereum offer different features and risk profiles. Some people buy cryptocurrency as a long-term store of value; others trade it actively for short-term gains. The coin that makes sense for someone who can afford to lose their entire investment is not the same as the coin for someone investing retirement savings.
Before choosing any cryptocurrency, you need to understand what you are actually buying, how volatile it is, and what could cause you to lose money. This guide explains how different cryptocurrencies work and what factors matter when you are deciding whether to invest.
Key Takeaways
- Bitcoin and Ethereum are the two largest cryptocurrencies by market value, but size alone does not mean lower risk or better returns.
- Cryptocurrency prices can swing 10 to 50 percent in a single day, so only invest money you can afford to lose completely.
- Different cryptocurrencies serve different purposes — Bitcoin is designed as currency and store of value, while Ethereum powers smart contracts and applications.
- Scams and fraud are common in cryptocurrency markets, and there is no government insurance if an exchange fails or your account is hacked.
- Tax reporting for cryptocurrency is required in most jurisdictions, and the rules are complex and still evolving.
How Bitcoin and Ethereum differ in purpose and risk
Bitcoin was created in 2009 as a peer-to-peer electronic cash system. It has a fixed supply cap of 21 million coins, which is built into its code. Supporters argue this scarcity makes it a hedge against inflation; critics point out that scarcity alone does not create value. Bitcoin's price has risen from pennies to over $60,000 per coin at various points, but it has also crashed 70 to 80 percent from its peaks multiple times.
Ethereum launched in 2015 and serves a different function. It is a platform for running applications and smart contracts — self-executing agreements written in code. Ethereum's supply is not capped, and new coins are created continuously through a process called staking. Ethereum's price volatility is similar to Bitcoin's, but the underlying technology and use case are distinct. If you invest in Ethereum, you are betting on the platform's adoption for applications, not just on the coin as a store of value.
Smaller cryptocurrencies like Solana, Cardano, and Polkadot exist, each with their own technology and purpose. They are generally riskier than Bitcoin or Ethereum because they have smaller markets, less trading volume, and less established track records. A coin can lose 90 percent of its value or become worthless if the project fails or loses developer support.
Price volatility and what it means for your money
Cryptocurrency prices move based on news, regulation, market sentiment, and sometimes coordinated buying or selling by large holders. In traditional stock markets, a 5 percent daily move is considered extreme. In cryptocurrency, a 10 to 20 percent move in a single day is normal. A 50 percent swing in a week is not uncommon.
This volatility creates both opportunity and danger. If you buy Bitcoin at $40,000 and it rises to $60,000, you have a 50 percent gain. If it falls to $20,000, you have a 50 percent loss. The longer you hold, the more time you have to recover from a dip — but you also have more time to experience a crash. Someone who bought Bitcoin at its peak in late 2017 did not see their money return to that level until 2021, a wait of over three years.
Financial advisors generally recommend that cryptocurrency should represent only a small portion of a diversified portfolio — often 5 percent or less — because the risk of total loss is real. If you cannot afford to lose the money you are investing, cryptocurrency is not an appropriate place to put it.
Scams, exchange failures, and security risks
Cryptocurrency markets have minimal regulation compared to stock markets or banks. There is no Securities and Exchange Commission (SEC) approval process for most coins, no Federal Deposit Insurance Corporation (FDIC) insurance if an exchange fails, and no central authority to recover your money if you are defrauded.
Common scams include pump-and-dump schemes, where promoters hype a coin to drive up the price, then sell their holdings and disappear. Fake coins and tokens are created to mimic legitimate projects. Phishing attacks target people's exchange accounts and digital wallets. If someone gains access to your private keys or seed phrase, they can steal your coins, and there is no way to reverse the transaction.
Exchange failures are also a real risk. In 2022, FTX, one of the world's largest cryptocurrency exchanges, collapsed suddenly, and customers lost billions of dollars. Funds held on an exchange are not the same as funds held in your own wallet — you are trusting the exchange to keep your coins safe and solvent. Some people reduce this risk by holding cryptocurrency in a personal hardware wallet rather than on an exchange, but this requires technical knowledge and carries its own risks, such as losing access to your wallet.
Regulatory uncertainty and tax obligations
Cryptocurrency regulation is still developing. The U.S. Internal Revenue Service (IRS) treats cryptocurrency as property, not currency, which means every transaction — including trades between different coins — is a taxable event. If you buy Bitcoin for $10,000 and sell it for $15,000, you owe capital gains tax on the $5,000 profit. If you trade Bitcoin for Ethereum, that is also a taxable event, even though you did not convert to dollars.
Tax reporting is complex because you must track the cost basis and sale price of every transaction, and the holding period determines whether you pay short-term or long-term capital gains tax rates. Many people underestimate their tax liability or fail to report cryptocurrency transactions altogether, which can result in penalties and interest from the IRS.
Regulation is also changing. Some countries have banned cryptocurrency entirely. Others are developing frameworks for taxation and consumer protection. In the United States, the SEC and Commodity Futures Trading Commission (CFTC) are still defining which cryptocurrencies are securities and which are commodities, which affects how they can be traded and taxed. A change in regulation can cause prices to swing sharply.
Diversification within cryptocurrency and across your portfolio
If you decide to invest in cryptocurrency, diversification matters. Holding only one coin concentrates your risk. Bitcoin and Ethereum are less correlated with each other than smaller coins are, so holding both reduces volatility somewhat. However, all cryptocurrencies tend to move together during market crashes — when Bitcoin falls 30 percent, most other coins fall too.
Diversification also means not putting all your money into cryptocurrency. A common framework is to hold cryptocurrency as a small portion of a larger portfolio that includes stocks, bonds, and other assets. This way, if cryptocurrency crashes, your entire financial plan does not collapse. The specific percentage depends on your age, income, and how much risk you can tolerate.
Dollar-cost averaging — investing a fixed amount at regular intervals rather than all at once — can reduce the impact of buying at a peak. If you invest $500 per month in Bitcoin, you will buy more coins when the price is low and fewer when it is high, which smooths out your average purchase price over time.
Questions to ask before you invest
Before putting money into any cryptocurrency, ask yourself these questions: Can I afford to lose this entire amount? Do I understand what this coin does and why it has value? How long am I planning to hold it? What would cause me to sell? What is my plan if the price drops 50 percent?
If you cannot answer these questions clearly, you are not ready to invest. Cryptocurrency is not a get-rich-quick scheme, despite what social media promoters claim. People who have made money in cryptocurrency often did so by holding through multiple boom-and-bust cycles, or by taking on risk they could afford to lose.
Frequently Asked Questions
Is Bitcoin safer than other cryptocurrencies?
Bitcoin has the longest track record and largest market, which means more liquidity and less risk of the network failing. However, "safer" does not mean safe — Bitcoin's price is still highly volatile, and you can lose money. Smaller coins are riskier because they have less trading volume and less established technology, but that does not make Bitcoin a may provide investment.
Should I invest in cryptocurrency instead of stocks?
Cryptocurrency and stocks serve different roles in a portfolio. Stocks represent ownership in companies with revenue and earnings. Cryptocurrency is a newer asset class with different risk and return characteristics. Most financial advisors recommend holding both stocks and bonds as your core portfolio, with cryptocurrency as a small, optional addition if you understand the risks.
What happens if I lose my password or wallet?
If you lose access to your cryptocurrency wallet, your coins are locked away permanently. There is no customer service to reset your password or recover your account the way there is with a bank. This is why security and backup are critical — but storing backups also creates risk if someone finds them. Research wallet security thoroughly before moving large amounts of cryptocurrency.
Can I make money day trading cryptocurrency?
Some people do, but most lose money. Day trading requires timing the market correctly repeatedly, paying transaction fees on every trade, and managing tax liability on short-term gains. The odds are against individual traders, especially those new to cryptocurrency. If you are considering day trading, start with money you can afford to lose and track your actual results, not just your wins.
How do I report cryptocurrency on my taxes?
The IRS requires you to report all cryptocurrency transactions, including trades between coins. You must track your cost basis and sale price for each transaction and report capital gains or losses on your tax return. Many people use cryptocurrency tax software to calculate their liability. If you are unsure, consult a tax professional who understands cryptocurrency, because mistakes can result in penalties.
