Crypto trading bots run fixed rules 24/7; copy trading repeats the trades of a person, AI agent or strategy you choose to follow. Bots execute logic, copy trading follows judgment. Both save you from staring at charts, but they fail in different ways, and picking the wrong one is a common and expensive mistake.
This post explains what each one is, when each makes sense, and the three questions that should decide between them. It also covers two newer options: writing rules in plain language, and mirror trading with an AI check in front of every trade.
What is a crypto trading bot?
A trading bot is a program that executes a fixed strategy. You define the rules (entry, exit, size, leverage) and the bot follows them around the clock without sleeping, panicking or revenge trading.
The strategies that tend to last are unglamorous:
- Grid bots place buy and sell orders at fixed intervals around a price and profit from sideways chop.
- DCA bots buy a fixed amount on a schedule and ignore price.
- Arbitrage bots exploit price gaps between venues, which professionals have mostly closed.
- Trend-following bots buy on a moving-average crossover and sell on the reverse.
A bot has no human in the loop. If the market changes character, it keeps doing what it did yesterday until you step in.
What is copy trading?
Copy trading repeats a human or AI source in real time. When the source opens a position, your account opens the same one. When it closes, you close. BottomUP's version is called mirror trading: you subscribe to creators (human traders, AI agents or algorithmic strategies) and their trades open in your own OKX account at your size.
The strategy is whatever the source decides today, and that can change. A momentum trader might switch styles mid-month without telling anyone, and a plain mirror follows them. (More on this in what is auto copy trading.)
On BottomUP, Foxy Shield scores every incoming mirrored trade and opens it at full risk, reduced risk or not at all, so drift gets checked before it reaches your account.
How do trading bots and copy trading compare?
| | Trading bot | Copy / mirror trading | | --- | --- | --- | | Strategy source | Rules you or a vendor wrote | A human, AI agent or algorithmic creator | | Adapts to new conditions | No, until you re-tune | Yes, as fast as the source does | | Runs 24/7 | Yes | Yes, if the source trades 24/7 | | Risk control | What you coded | What the platform checks and your own limits | | Explainability | The code is visible | Depends on the source and the platform | | Setup skill | High | Low | | What you pay for | Code that runs | Someone else's judgment |
The headline: bots execute logic, copy trading executes judgment. Logic is reliable but slow to adapt. Judgment adapts but is less reliable.
Which should you choose? Three questions decide
1. Do you have a view on the market, or do you trust someone who does?
If you have a view ("this market chops sideways for months"), a bot is the right tool: you encode the view into rules. If you do not, but you can find a source with a measured record, following is the right tool: you delegate the view. If you have neither, no tool will save you.
2. What happens when the market changes?
Bots break quietly. A grid bot in a sudden trend loses on every cycle; a trend follower in a choppy market loses on every whipsaw. You have to notice. Copy trading adapts as fast as the source does, which can be too fast. A check in front of each trade is what protects you when the source moves too fast.
3. How much do you care why a trade happened?
A bot can tell you exactly why every trade fired: it is in the code. Many copy trading sources never explain themselves. If you want to learn from your trades, rules you wrote yourself are the better classroom.
Is there a middle ground between bots and copy trading?
Yes: rules written in plain language. On BottomUP, Tickets let you describe conditions in words, such as price levels, candle closes, RSI, MACD, moving averages, Bollinger bands, VWAP, ATR, volume, position PnL or drawdown, funding or time. Conditions can combine with all or any logic, run in sequence, or require something to hold "for at least N minutes." Actions include close, partial close, move stop, take profit, open or flip, cancel, notify, or ask first. Foxy watches them 24/7, and nothing runs until you press Start watching.
That gives you the transparency of a bot without writing code.
When should you combine them?
A pattern many traders use: rules for the base layer, following for the active layer.
Run simple, scheduled buying or rule-based exits for the core of your portfolio. Put a smaller share into creators you mirror for the active part, and cap the number of open mirrored trades so one bad creator cannot dominate the account.
This works because the two layers fail differently. A scheduled buyer's worst day is a crash, which it turns into a lower average cost. A followed trader's worst day is a revenge-trade sequence, which a per-trade check is built to catch. See AI portfolio management for how the layers fit together.
The honest pitch for each
Pick a bot if you have a clear market view, will review the strategy regularly, want to know why every trade fires, and accept that the bot behaves the same when the market changes.
Pick copy or mirror trading if you do not want to build a strategy yourself, trust the platform's checks and records, and are willing to spread across a few creators rather than one star.
Pick both if you want a base layer that runs forever and an active layer that adapts.
The weakest option in all cases is "I'll trade by hand when I have time."
Frequently asked questions
What is the difference between a trading bot and copy trading?
A trading bot follows fixed rules that you or a vendor wrote. Copy trading repeats the live trades of a source you choose. Bots are predictable but do not adapt; copy trading adapts but depends on the source's judgment.
Does BottomUP offer trading bots?
BottomUP's Marketplace includes algorithmic strategies alongside human traders and AI agents, and you can mirror any of them. You can also write your own rules in plain language with Tickets.
Do I need API keys?
Not on BottomUP. You connect your OKX account with OKX sign-in in two clicks. The connection can read balances and place trades, never withdraw.
Which is safer, bots or copy trading?
Neither is safe by default. A bot is only as good as its rules, and a mirror is only as good as its source and the checks in front of it. Both can lose money.
BottomUP, Inc. is a Delaware company running a marketplace for non-custodial portfolio management. Foxy never says buy or sell, and nothing here is investment advice. Mirror trading is not offered to U.S. persons or in sanctioned regions. Trading carries a high risk of loss. See the risk disclosure.
