How to check a crypto token before you buy it
Most people buy tokens because the price is moving, not because they checked anything. This five-minute checklist catches the most common problems.
- If you cannot explain in one sentence what the token does and why you are buying it, skip it.
- Check where it trades, how big it is, how many coins are still locked and how easy it is to sell.
- A sudden price jump, urgent messages and guaranteed returns are warning signs.
Step 1: What is it, in one sentence?
Write down what the project does and how the token is used. If the explanation is only about price going up, that is a red flag. Use the project’s official website, documentation and the original announcement, not social media posts about it.
Step 2: Where does it trade?
Is it listed on large, well-known exchanges, or only on obscure ones and a single decentralised pool? Very new tokens on one venue are the riskiest. Check that you have the correct token: scammers copy names and tickers. Confirm the contract address from the official website.
Step 3: How big is it and how much is locked?
Look at market cap, fully diluted valuation and the unlock schedule. A small circulating supply with a huge FDV means many future coins could hit the market. See Market cap, volume and liquidity explained.
Step 4: Can you actually sell it?
Check daily volume compared with market cap and the depth of the order book. If you buy 1,000 USDT, how much would the price move when you sell it back? On decentralised tokens, test with a small amount first. Some malicious tokens let you buy but not sell, known as honeypots.
Step 5: Who holds it?
On a blockchain explorer you can see the largest holders. If a few wallets hold most of the supply, they can crash the price by selling. Some of those wallets are legitimate (exchanges, vesting contracts), so look for labels.
Step 6: Who is behind it, and has it been reviewed?
Is the team public with a verifiable track record? Has an independent firm audited the smart contract? An audit lowers some risks but does not make a token safe. It does not protect against a team that decides to sell.
Step 7: Look at the price history
Did the price rise sharply in days or hours? Use Check a coin: if the coin is up massively this week or sitting at the top of its range, you would be chasing, which is when most late buyers lose.
Step 8: Warning signs
- Promises of guaranteed or “risk-free” returns.
- Pressure to act now, or a countdown timer.
- Anonymous team and no documentation.
- Unlimited ability to mint new tokens or change rules.
- Telegram or Discord admins promoting the price.
Common mistakes
- Buying because a coin is trending on social media.
- Trusting an audit badge without reading what it covers.
- Skipping the sell test.
- Putting in more than you can afford to lose.
Check recent trend, stretch and volume, then size the position so a loss is one you accept.
