How to choose a coin before you trade

ChooseChoosing · 9 min read

Choosing a coin before you trade means you can explain, before you look at a chart, what you are buying and what would make you get out. If the answer is only “people say it will go up”, you have not chosen anything. You are following someone else.

Disclaimer: this is a way of thinking, not a recommendation to buy or sell. Bitcoin, Ethereum, Solana, BNB, and every other coin can fall sharply, in extreme cases to nothing. Do not use rent money, borrowed money, or cash that must still be there next month.

1. Separate three decisions

  1. What the asset is. What the coin is used for, who uses it, and what happens if the network or the company behind it fails.
  2. How much you can lose. Write that amount before you open an order. That is the position limit, not a profit target.
  3. When the plan is cancelled. One sentence: “I exit if …” It can be a price you already picked, or a fact (the network stays down, a key leaks, you no longer understand the product).

Read the chart only after those three are written down. The chart does not replace the first question.

2. Questions you should be able to answer

  • Use. Do people pay network fees with this coin, or does it mostly change hands because someone hopes the price rises? Both are worth studying. The risks differ.
  • Supply. Is there a cap, or do new coins keep appearing? Who receives new coins (miners, validators, a team, or early holders)? Read the current figure in the project’s own docs on the day you check, not from an old screenshot.
  • Liquidity. On the exchange you already bookmarked, does your size move the price a lot? A thin market makes you buy high and sell low even when the “last price” looks fine.
  • Where you keep it. Do you understand the difference between an exchange balance and coins in your own wallet? Wrong-network withdrawals are covered in the deposit guide.
  • Who you are trusting. Is there official documentation, or only a chat promising a fixed return? A guaranteed profit is a reason to close the page.

3. Size the position before the buy button

A practical beginner limit: an amount that, if it went to zero, would still leave this month’s bills paid and would not put you in debt to “make it back”. Make the first try smaller than that. One coin you understand is more useful than ten names you only saw on a trending list.

Do not raise the size because the price just moved. That move is not proof you finished choosing.

4. Working order, one coin

  1. Write the name and the official documentation link (not someone else’s video).
  2. One paragraph: what this coin is used for.
  3. Note the supply from an official source, with the date.
  4. Open the order book on the official exchange. See whether your size is absorbed without a large gap from the last price.
  5. Write the loss limit in money, not in a percent you never convert into cash.
  6. Write the cancel condition.
  7. Only if every line is filled may you place an order, and only up to the limit you wrote.
Skip the coin that fails any line. Skipping is not the same as missing out. It means you do not yet have a reason you can stand behind.

5. What is not a reason to choose

  • Rank on a “top gainers today” list.
  • A picture promising a multiple in a short time.
  • A stranger asking you to send coins to their address “so they can manage it”.
  • A name that looks like a major coin (one extra letter, or a fake domain). Check the spelling in the official docs.
  • Fear of missing out because a friend already bought.

6. After you choose, then read the price

Price analysis answers “when I enter and where I am wrong”, not “this coin is certainly good”. Write the entry, the exit limit, and a one-sentence reason. If price touches the exit, exit. Do not move the limit only because it feels uncomfortable.

The same checklist applied to four assets beginners hear about most is in how to read Bitcoin, Ethereum, Solana, and BNB. That page is not a ranking of which one is best.

Other basics: fake sites · rejected KYC · 2FA and withdrawals · missing deposits · comparing exchanges · choosing a coin · BTC, ETH, SOL, BNB.
