Why is one amount enough to copy one trader but not another?

01Why the advertised minimum doesn't answer your question

The minimum you see advertised is about one order. On Bybit's Copy Trading Classic, when you choose Advanced Copy Mode you decide how much of your own money goes into each copied trade. Bybit calls this the order cost: the part of your money the exchange sets aside while that copied trade is open, and gives back when it closes. (That set-aside money is what traders call margin.) The allowed range depends on the trader's rank — the help page's own example is a Bronze Master Trader with a minimum of 10 USDT and a maximum of 2,000 USDT per trade. That tells you what one order may cost you. It says nothing about how many orders that person fires off in a week.

Your real requirement is the order cost multiplied by the number of orders that will be open at the same time, plus whatever is left over for losses, fees and funding. Two traders can both accept a 10 USDT order and still need completely different budgets from you. If the whole idea of copying is still new, the general mechanics are on our copy trading overview; this page is only about matching your own amount to one specific trader.

02How your money splits across several trades at once

Bybit copies the trader's orders one at a time. Same-direction orders on the same pair get merged into one position with an average entry price, but each of those orders still took its own order cost from your balance when it was placed. A trader who enters BTC once and then waits for the exit is cheap to follow. Another trader works differently. They open three pairs, and on each pair they add twice after the first entry. That is nine orders, and each one takes its own order cost from your balance before any of them closes.

Here is what that looks like with a 200 USDT budget in Advanced Copy Mode and an order cost of 20 USDT. These are made-up traders, used only to show the arithmetic.

The third row is the situation people run into and don't understand. Nothing was wrong with your deposit and nothing was wrong with the trader — you simply ran out of orders. Bybit lists insufficient funds in the Copy Trading account as one of the standard reasons a trade is not copied, and that leaves you holding part of someone's plan instead of all of it. A trader who averages down needs even more room, which is its own question: see how much spare money a follower needs when the trader averages down.

03The smallest order the exchange will actually accept

There is a second limit, and it comes from the contract itself, not from the copy settings: every order has a minimum size. Bybit's example is BTCUSDT with a minimum of 0.001 BTC. Your order cost and your leverage together decide whether a copied order reaches that size. With bitcoin somewhere around 80,000 USDT (an illustrative price), 0.001 BTC is roughly 80 USDT of position — at 10x that needs about 8 USDT of margin, at 2x it needs about 40 USDT. Same minimum, very different demand on your balance.

If the order cost and leverage you chose cannot produce the minimum size, the copy simply fails, and Bybit sends you a copy-failed email saying so. The other mode, Smart Copy, works out your size from your balance instead of a fixed amount you choose. If that calculation comes out smaller than the smallest order the contract allows — 0.001 BTC on BTCUSDT — Bybit places that smallest order anyway. So on that trade you put in a bigger slice of your money than the trader put in of theirs, even though the two positions look matched on screen. This is the same gap described in fixed amount versus fixed ratio copying.

04Checking you have a buffer for the whole sequence

Margin is not the only claim on your balance. Bybit says the trading fee and the funding fee in copy trading are the same as on its normal derivatives platform. Both are taken from the same balance, so they shrink the money available for the next copied order. The trader also takes a share of the profit they make for you. Bybit's help page doesn't give one number for every trader, so check what that person charges in the app before you start copying. A trade that is already losing also eats into the money sitting free in your copy account, so the next order from that trader can be rejected even though you never withdrew anything.

A couple of practical details about where the money sits. Bybit's Copy Trading Classic works in USDT only, bonuses and coupons cannot be used for these trades, and your funds move into a separate Copy Trading account when you start copying and come back after you stop and all positions are closed. You can follow up to 10 traders at once, but the settings and orders for each are kept separate — splitting 150 USDT across three traders gives each of them a very thin balance, not one shared pool.

1. Read the trader's open positions, not just the profit curve

   On the trader card, look at how many pairs they hold simultaneously and whether several entries appear on the same pair. That count is your multiplier. Our guide to choosing a trader to copy covers what else is worth reading on that page.

2. Open the copy settings and find the allowed order cost

   In Advanced Copy Mode you type a fixed order cost per trade; the minimum and maximum depend on that trader's rank, so check the actual range shown for the person you picked rather than a number from an article.

3. Multiply, then add a third

   Order cost × the number of orders you expect open at once is the floor. Adding roughly a third on top leaves room for fees, funding and unrealized losses before orders start getting rejected.

4. Test the minimum order size at your leverage

   Place the settings and watch the first few copies. If you get copy-failed emails about minimum order size, the usual fix is to raise the order cost a little, so each copied order is big enough to be accepted. Higher leverage would also get you over the minimum, but it makes the position bigger behind the same money, so your loss grows at the same speed — and leverage in copy trading follows the trader's orders anyway.

5. Set your exit limit before the first trade, not after

   Bybit's Perpetual Copy Stop Loss closes things out when your equity with that trader falls to the level you set — their example is a 400 USDT stop on 1,000 USDT of equity, triggering at 600 USDT. Note that reducing your investment below the stop amount deletes it.

05What to do when your amount doesn't fit that trader

You have three honest options. Lower the order cost so the full sequence fits, which also shrinks every result in proportion. Add funds so the structure fits as it is. Or pick a trader whose order structure matches the money you have — someone who holds one or two positions at a time is simply cheaper to follow than someone running a basket. The one thing that really hurts is doing nothing: keeping an order cost that cannot cover the whole sequence, and finding out only when half the trader's plan is sitting in your account.

All of this is visible before you commit anything. The copy settings screen shows the allowed order cost range for the trader you selected, and the trader's page shows what they currently hold. If you want to look at the real numbers rather than an example, sign up on Bybit and open the card of a trader you are considering — more on how the exchange itself is set up is in our Bybit overview. Copy trading and futures are not offered everywhere — check during sign-up that Bybit and its copy trading are available where you live.
