3Commas Review: How to Judge It

What 3Commas is, in general terms

As we understand it, 3Commas is a service that connects to crypto exchanges through API keys and runs bots on your behalf, with bot types such as grid and dollar-cost averaging bots. People search for a review, so this page uses that word, but it contains no verdict. We have not run the product. It explains what to check and how.

A review is only as useful as the reviewer's evidence. A trustworthy one says what was done, with what amount, for how long and on what date. If you read any review of any bot service, look for those four things, and notice whether the writer earns a commission when you sign up. Our own method is on the method page.

We name the product only so you can find this page. We state no prices, plan names, fees, supported venues, results, user numbers or ratings, because they change and we have not checked them. Everything below is about the product class.

The risks of this kind of product

• Third-party access. Any service that holds API keys for many users is an attractive target. Treat a key as something that can leak and limit what it can do: trading permission only, no withdrawals, and an IP allow list where offered.
• Reviews can be paid. A review that links to a sign-up may pay its author. That does not make it wrong, but it is a reason to weigh the evidence in it, not the tone.
• Costs are paid in every month. A subscription, a performance share or a trading fee lowers the result whether or not the month was good. The worked example below shows the size of the effect.
• A backtest is not your result. A backtest shown by a vendor or a strategy author was not run on your account size, your fees or your delays. See backtesting and overfitting.
• Someone else's bot is not your bot. You may not see its full rules, you may not know when its author changes it, and a record can be several versions joined together. A bot you build yourself has other risks, mainly mistakes, but you know what you set.

Worked example: how a flat fee changes break-even

Everything here is made up. It is not the price of 3Commas or of any other product. Say a service costs $30 a month, which is $360 a year. The monthly return needed just to pay the fee is the fee divided by the account.

Calculated by us on 31 Oct 2026, exact. The same $30 costs 6.00% of the smallest account and 0.20% of the largest, so a small account carries a much heavier hurdle. If the gross return in a month is lower than the fee percent, the month is a loss even when every trade was a winner. If a bot trades often, add trading fees, spread and slippage on top. Use the break-even calculator with your own figures.

A checklist for the vendor's current pages

Read these on the vendor's own pages on the day you decide, and write down the date you read them.

• Costs. Every charge: subscription, per-trade, performance share, withdrawal, and what happens to a charge if you cancel. Convert each to a percent of the account you would really use.
• Permissions. What access you must give. If it uses API keys, which permissions are needed. Withdrawal permission should not be needed to run a bot, so ask why if it is requested. Restrict keys to trading only where the venue allows, and use an IP allow list if it is offered.
• Custody. Where the money sits while it is trading: with the venue you chose, or with the vendor. Whoever holds it can be hacked, can be restricted or can fail.
• Venues and markets. Which ones it works with today, and whether your account type and country are accepted.
• Terms. Refunds, liability, what happens to open positions if the service goes down, and how a bot behaves when the connection is lost.
• Records. Whether you can export every order and fee, so you can check the result yourself and prepare tax records. Tax treatment depends on where you live: ask a qualified person.
• Security history. Look for the vendor's own statements on security incidents and what they changed afterwards, on its current pages and in news from a source you trust, and note the dates.
• Bot types. What each bot type does, what it needs in capital if every step fills, and whether you can see the maximum exposure before you start. See DCA bot for how to compute that.

How to test it with almost no money

Judge a bot service by your own small test, not by other people's reviews. Use one exchange sub-account with only the test amount, a key with trading permission only, and one simple bot type. Keep a log of every order and every charge.

1. Use a demo or paper mode if one exists, and say to yourself that its fills are cleaner than live ones. See paper trading and demo accounts.
2. Next use an amount you can afford to lose completely, on a key with trading permission only.
3. Record every order, fee and the fee you paid the vendor. After a few weeks compute the result yourself from your own records and compare it with what the dashboard said.
4. Check the drawdown, not only the final number. A smooth rise with one deep fall is a different product from a steady one.
5. Decide the loss at which you will switch it off before you start, and write it down.

What this page does not tell you

It does not say 3Commas works, fails, is safe or is risky. It does not compare it with any other product. It has no figures from the vendor. Its numbers are made up to show how a fee and a small account interact, and nothing here is a recommendation to use or avoid anything. Crypto-assets and leveraged products can lose all the money put into them, and past or simulated results are not a guide to future results.
