Crypto Copy Trading Bots Compared: GMGN, Trojan, Krypto Mirror
An on-chain copy trading bot watches a wallet you choose and repeats its trades from your own wallet, at your own size. The bots differ in fees, chains, limits and how they handle sells, but the bigger question is the one no bot answers for you: is the wallet worth copying?
Disclosure: Krypt makes Krypto Mirror and Krypto Bot. Everything about the other products comes from their own sites, docs or repositories, checked in November 2026. Prices and features change often, so confirm on their site before you choose. No affiliation with any of them is implied.
At a glance (November 2026)
| Runs as | Chains for copying | Fee | Notes from its docs | |
|---|---|---|---|---|
| Krypto Mirror | Desktop app (Windows, macOS, Linux) | Solana, Robinhood Chain, BNB Smart Chain | 0.5% per trade | Wallet scanner and wallet checks built in |
| Krypto Bot | Desktop app (Windows, macOS, Linux) | Solana, Robinhood Chain, BNB Smart Chain | 0.5% per side | Copy trading starts on paper; Wallet Scout ranks wallets after latency and fees |
| GMGN | Web + Telegram | Solana only | 1% per copy trade | Up to 10 copy tasks; a task pauses after 3 failed copies |
| Trojan | Web terminal | Solana | 1% per trade | Copy by % of the target's size or a fixed amount; docs say it doesn't work with every wallet |
Network fees and priority tips are extra everywhere.
Why copying never matches the original
Your copy can only start after the wallet's trade lands on-chain, so you buy later, often at a higher price, and the wallet you follow may be selling into exactly that demand. Add a 0.5% to 1% fee each way and a wallet with a modest edge can easily become a losing one to copy. That's why the tools that rank wallets by what copying them would have made after latency and fees are more useful than ones that rank by the wallet's own profit.
How to pick a wallet worth copying
- Lots of trades over weeks, not one huge win.
- Consistent position sizes. Wild sizing makes copies unpredictable.
- No sign it's a creator or insider wallet that buys its own launches and sells into followers.
- Liquid tokens. If it trades coins with tiny liquidity, your copy moves the price against you.
- Start with small sizes and two or three wallets, not one with everything.
When each one fits
- GMGN if you're on Solana, already use its web terminal, and want copy trading next to its other tools.
- Trojan if you trade on Solana from its terminal and want simple %-of-target or fixed-size copies.
- [Krypto Mirror](/blog/krypto-mirror-setup-guide) if you want a desktop app that does just this (find, check and copy wallets) on Solana, Robinhood Chain or BNB Chain at 0.5% per trade.
- [Krypto Bot](/blog/krypto-bot-setup-guide) if you want copy trading inside a full terminal, and want to run it on paper first.
FAQ
Does copy trading crypto actually work?
Copy trading repeats a wallet's trades; it can't repeat its results. You enter later and pay fees, so most wallets look worse to copy than their own numbers suggest. Test with small sizes, or on paper where the tool allows it.
What fees do copy trading bots charge?
As of November 2026: GMGN and Trojan charge 1% per trade; Krypto Mirror 0.5% per trade. Network fees and priority tips are extra.
Can I copy trade on BNB Chain or Robinhood Chain?
GMGN's copy trading is Solana-only per its docs. Krypto Mirror and Krypto Bot copy on Solana, Robinhood Chain and BNB Smart Chain.
How many wallets should I copy?
Two or three with small sizes is a sensible start. It limits the damage if one wallet turns out to be an insider dumping on followers.
