No single cryptocurrency is right for everyone, and this guide cannot tell you which one to buy
The question "what crypto should I buy" does not have a one-size-fits-all answer because it depends on your financial situation, how much risk you can handle, and what you are trying to do with the money. This guide explains the factors people actually consider when researching cryptocurrencies, what information exists about different coins, and where that information lives. It does not recommend specific coins or tell you whether any particular purchase is a good idea.
Before you research any individual cryptocurrency, you should understand what you are looking at: a highly volatile asset with no may provide value, no insurance if you lose access to it, and no customer service if something goes wrong. People have lost their entire investment in crypto. That risk does not change based on which coin you pick.
Key Takeaways
- Cryptocurrency prices move based on market demand, news, and speculation — not on earnings or assets backing the coin the way stocks are backed by company value.
- Each cryptocurrency has a whitepaper (a technical document explaining what it does) and a market cap (total value of all coins in circulation), both of which are public and searchable.
- Larger cryptocurrencies like Bitcoin and Ethereum have longer price histories and more public information, while smaller coins carry higher risk and less established track records.
- You can research a coin's history, the team behind it, and what problem it claims to solve, but past performance does not predict future results in crypto markets.
- Before you buy any cryptocurrency, you need a plan for how you will store it safely and what you will do if the price drops significantly.
The difference between market cap and price per coin
When you see a cryptocurrency listed with a price — Bitcoin at $40,000 or Ethereum at $2,000 — that price alone does not tell you whether the coin is expensive or cheap. What matters is the market cap, which is the total value of all coins in circulation. You calculate it by multiplying the price per coin by the total number of coins that exist.
Bitcoin has a market cap in the hundreds of billions of dollars because there are only 21 million Bitcoin that will ever exist, and the price per coin is high. A different coin might cost $0.50 per coin but have billions of coins in circulation, giving it a market cap in the hundreds of millions. The cheaper-looking coin is not necessarily a better deal — it depends on the total value of the network and what the coin is used for.
Market cap data is available on sites like CoinMarketCap and CoinGecko, which list cryptocurrencies ranked by total value. These sites also show price history, trading volume (how much of the coin is being bought and sold), and links to each coin's official information.
What a whitepaper tells you about a cryptocurrency
Every established cryptocurrency has a whitepaper — a technical document that explains what the coin does, how it works, and what problem it is meant to solve. Bitcoin's whitepaper, published in 2008, describes it as a peer-to-peer electronic cash system. Ethereum's whitepaper explains how it enables programmable contracts on a blockchain. These documents are public and usually linked from the coin's official website.
Reading a whitepaper is not required to own a cryptocurrency, but it tells you what the creators intended the coin to do. If the whitepaper describes a use case you do not understand or do not believe will work, that is information. If the coin has no whitepaper or the official website is unclear about what the coin does, that is also information — it suggests the project may not be serious or transparent.
You do not need to understand every technical detail in a whitepaper. Look for: what specific problem the coin solves, how it is different from other cryptocurrencies, and whether the stated use case makes sense to you. If you cannot find a whitepaper or a clear explanation of purpose, that is a reason to research further before considering a purchase.
How to research the team and history behind a coin
Some cryptocurrencies are created by named individuals or organizations with public track records. Bitcoin was created by someone or a group using the pseudonym Satoshi Nakamoto, whose identity remains unknown. Ethereum was created by Vitalik Buterin and others whose names and backgrounds are public. Other coins are created by anonymous teams or companies, which carries different risks.
You can research a coin's history by looking at: when it was created, what changes have been made to it over time, whether the team is still active, and what the coin's price has done during major news events or market crashes. Sites like GitHub show the technical code behind many cryptocurrencies and how often developers are updating it. A coin that has not been updated in years may be abandoned.
News archives and cryptocurrency forums like Reddit's r/cryptocurrency contain discussions of past controversies, scams, or technical problems associated with specific coins. This is not always reliable — people post opinions and rumors alongside facts — but it gives you a sense of what issues a coin has faced and how the community responded.
The relationship between use case and price movement
Cryptocurrency prices move based on supply and demand, not on earnings or assets the way stock prices do. A company's stock price reflects expectations about future profits. A cryptocurrency's price reflects what people believe others will pay for it in the future, combined with actual use of the coin for transactions or contracts.
Bitcoin's price has historically moved based on news about regulation, adoption by major companies, and macroeconomic events. Ethereum's price moves partly based on activity on its network — when more people use it for contracts and transactions, demand for Ethereum increases. Smaller coins often move based on social media attention, celebrity endorsements, or speculation that the price will rise.
This means you cannot predict a cryptocurrency's price the way you might predict a company's stock price by analyzing financial statements. You can look at historical price patterns and trading volume, but past performance does not indicate future results. A coin that rose 500% last year may fall 80% this year.
Comparing cryptocurrencies by size and risk level
Cryptocurrencies are often grouped by market cap: large-cap coins like Bitcoin and Ethereum, mid-cap coins with market caps in the billions, and small-cap coins with market caps in the millions or less. Larger coins generally have longer price histories, more public information, and more established use cases. They also tend to be less volatile — their prices move less dramatically day to day.
Smaller coins carry higher risk because they have less trading volume, less public information, and less established track records. A small-cap coin can rise 1,000% or fall to near-zero. Some small coins are legitimate projects with real use cases; others are created primarily to make money for their creators at the expense of buyers.
There is no rule that says you should only research large-cap coins or only small-cap coins. The point is to understand what information is available for each. For Bitcoin or Ethereum, you can find years of price data, technical analysis, and news coverage. For a coin created last month with a market cap of $10 million, you may find almost no independent information.
Where to find information about specific cryptocurrencies
Official sources include the coin's website, whitepaper, and social media accounts (Twitter, Discord, or Telegram). These tell you what the creators claim about the coin but are not independent verification.
Third-party information sources include CoinMarketCap and CoinGecko (price and market data), blockchain explorers like Etherscan (transaction history and network activity), and financial news sites that cover crypto. Reddit communities and cryptocurrency forums contain discussion and analysis, though they also contain speculation and misinformation.
Academic research and technical analysis are available through university publications and financial research sites, though these vary widely in quality. Some analysis is rigorous; some is speculation dressed up as analysis. The more sources you read, the better sense you get of what is consensus and what is outlier opinion.
What to decide before you research any specific coin
Before you spend time researching individual cryptocurrencies, decide what you are actually trying to do. Are you researching coins as a long-term investment you plan to hold for years? Are you interested in using a specific coin for transactions? Are you researching because you are curious about the technology? Your answer changes what information matters.
You should also decide in advance how much money you can afford to lose without affecting your life. Cryptocurrency is volatile enough that you should only invest money you do not need for bills, emergencies, or near-term goals. If you cannot afford to lose the money, do not invest it in crypto, regardless of which coin you research.
Finally, plan how you will store the cryptocurrency safely. Different storage methods (exchanges, hardware wallets, software wallets) have different security tradeoffs. If you lose access to your coins through a lost password or a hacked account, there is no customer service to recover them. Understanding storage before you buy means you are not scrambling to figure it out after.
Frequently Asked Questions
Should I buy the cheapest cryptocurrency I can find?
No. Price per coin does not indicate value or potential. A coin that costs $0.01 is not cheaper than a coin that costs $100 if the expensive coin has a smaller total supply. Look at market cap and what the coin is used for, not the price tag alone.
Is Bitcoin or Ethereum the safest cryptocurrency to research?
They have the longest track records and the most public information, which makes them easier to research. That does not mean they are safe investments — cryptocurrency is volatile and risky regardless of which coin you pick. Longer history means more data to analyze, not a may provide of future performance.
How do I know if a cryptocurrency is a scam?
Red flags include: no clear explanation of what the coin does, anonymous team with no verifiable background, promises of may provide returns, pressure to buy quickly, and no whitepaper or technical documentation. If you cannot find independent information about a coin from sources other than its official website, that is a reason to research further before considering it.
Can I research a coin and then decide not to buy it?
Yes. Research is not a commitment to purchase. Many people research cryptocurrencies extensively and decide the risk is too high or the use case does not make sense to them. That is a valid outcome of research.
Where do cryptocurrency prices come from?
Prices come from exchanges where people buy and sell coins. The price at any moment is whatever the last buyer and seller agreed on. Prices vary slightly between exchanges because each exchange has its own order book. Major news, regulation changes, or shifts in market sentiment can cause prices to move significantly in short periods.
