The full path: five stages and where each cost sits

Start with the overview. The process has five stages, each carrying a different kind of cost — which is why "working out the cost" cannot mean looking at fees alone.

Step 1: register with the code, the one irreversible step

Of the five stages, only the first is completely impossible to fix afterwards. The referral code must be entered at registration, and once the account exists there is no "add a referral code later" option in account settings.

The least error-prone route is to use the link carrying the code so the field fills in automatically, rather than typing it by hand — typing is where mistakes, omissions and someone else's code come from.

One more point: the referral code and BGB deduction are two layers, not a choice between two options. Entering the code lowers the fee tier first; enabling BGB deduction lowers it again. Only with both active do you reach the lowest cost.

Step 2: what KYC and security settings actually unlock

This stage costs nothing, but it determines whether you can move at all. Spot trading stays locked until KYC is complete, meaning without identity verification you cannot get through the spot purchase flow.

The practical advice is to complete two-factor authentication and your withdrawal password before your first deposit or withdrawal. The reason is simple: the risk of a brand-new account being compromised is highest right after opening, which is exactly the window in which you are funding it.

Verification itself is free. There is no KYC fee and no paid priority-review option.

Step 3: choosing a deposit method and where fees differ

There is no single best deposit method — only the one that matches your amount and how urgent it is. The four options have completely different cost structures.

For a first deposit the most efficient route is usually an on-chain transfer with the right network chosen: the platform charges nothing, so your only job is comparing network fees. At small amounts the difference barely matters; at larger amounts the network choice noticeably changes the cost.

Step 4: the two independent spot order thresholds

Once the funds are in, buying BTC on spot has two independent thresholds. Many beginners assume there is only one and only discover the second when the order is rejected.

Why two of them? Because they govern different things. Minimum quantity is a floor on size; minimum value is a floor on amount. When BTC is cheap, 0.0001 BTC might only be a few dollars and the value threshold is what blocks you. When BTC is expensive, 0.0001 BTC may already exceed 5 USDT, and now the quantity threshold is the one doing the work.

Another common misconception: maker and taker rates are the same. Spot limit and market orders both sit at 0.1%; the difference is in execution price, not the fee rate. So the claim that limit orders are cheaper because of fees is wrong — what limit orders save you is the spread.

The core calculation: real cost at different sizes

Now put everything together. The spot base rate is 0.1%, falling to 0.08% with BGB deduction; the referral code then takes 20% off that rate.

The point of this table is not the absolute amounts but the fact that the value of the rebate scales with your trading size. Saving 0.036 USDT at 100 USDT is invisible; saving 18 USDT at 50,000 USDT is a real cost. So the question "should I enable BGB deduction" is arbitrary at small sizes and worth a proper calculation at large ones.

A checklist before and after your first purchase

Work through these in order — each item can only be confirmed once the previous one is done:

1. Confirm the referral code is carried through. Look at the signup page once more before submitting, so the field is not blank.
2. Complete KYC. Without it the spot flow cannot be finished.
3. Enable two-factor auth and your withdrawal password. Before your first deposit or withdrawal, not after.
4. Decide the deposit method and network. Test small first, confirm arrival, then send the rest.
5. Check available balance. Available balance is what you can actually trade with; total balance is not always the same.
6. Confirm the fee rate has been applied. Check it on the fee page or the order ticket before submitting.
7. Check three things right after the order fills. Average fill price, the fee actually deducted, and whether the resulting quantity matches your expectation.
8. Write down the result of your first fill.Keep the average price and the actual fee so you have a baseline to compare the next trade against.

Summary

From registration to holding your first BTC there are five stages and four cost positions, and only the spot purchase itself is offset by the rebate — the on-chain network fee and the exchange spread on deposit are not. What really determines your cost is whether the code was entered correctly at registration, and whether your capital is large enough for fee optimisation to matter at all.

The beginner sequence is: confirm the referral code carried through → complete KYC → set up security → test a small on-chain deposit → confirm available balance and fee rate → place a first order at a comfortably compliant size. Early on the goal is to get the flow right once, not to drive the fee rate to its lowest point. If you have not registered yet, start through https://partner.bitget.com/bg/8cp8dcqu so referral code BTC9149 is carried in automatically, then enable BGB deduction and the spot fee rate falls to 0.08% with another 20% off, giving an effective cost of 0.064% — that is the saving on every trade, but no fee rate recovers a referral code entered incorrectly.
