Deposit and Signup Bonus Mechanics

"Deposit $1,000, get $200." The headline is the least informative part of the offer. Whether that $200 is worth anything is decided entirely by five clauses further down the page, and they vary enough between venues that two identically-advertised bonuses can differ by an order of magnitude in real value.

Here are the five, what each one does to the number, and the arithmetic that turns a headline into a decision.

1. Eligibility: are you the target?

Signup and deposit bonuses are acquisition spend. The venue is paying to convert someone who does not have an account into someone who does, which means the terms are usually written to exclude everyone else.

The standard restriction is new users only — and "new" is defined by the venue, not by you. Depending on the terms it can mean no prior account, no prior account from your IP or device, no prior deposit, or no account within some lookback period. If you have ever had an account there, assume you do not qualify until the terms say otherwise in writing.

Two adjacent restrictions worth reading for:

• Referral or code requirement. Many bonuses only attach if you signed up through a specific link or entered a code at registration. This can never be applied retroactively — it is the single most common way a genuinely available bonus is lost, and it costs nothing to get right.
• Jurisdiction. Exclusions are common and are usually enforced at withdrawal rather than at signup, which is the worst possible time to discover them.

2. Minimums: what you have to put up

Three minimums show up, sometimes all at once:

• Minimum deposit — the qualifying amount, often tiered so that larger deposits earn a larger bonus.
• Minimum trading volume — cumulative notional you must trade before the bonus is released.
• Minimum trade count — a number of trades, independent of size.

The deposit minimum is the easy one; it costs you liquidity, not money. The volume and trade-count minimums are where the actual price is hidden, and they deserve their own section.

3. Volume requirements: the real price

A volume requirement — the crypto equivalent of a casino wagering requirement — says the bonus is yours once you have traded some multiple of it. This is not a formality. It is the venue buying volume, and you are the one paying for it in fees and spread.

The arithmetic is simple and almost nobody does it:

## what a volume requirement actually costs
cost = required_volume * (fee_rate + expected_slippage)
net  = bonus - cost

Worked, with a $200 bonus and a requirement of $500,000 of notional:

## at a 4.5 bps blended fee and 2 bps of slippage
cost = 500,000 * 0.00065 = $325
net  = 200 - 325 = -$125

The bonus is negative. You would pay $325 to receive $200, and the venue books half a million dollars of volume it did not have. Change the requirement to $150,000 and the same bonus is worth 200 - 97.50 = $102.50 — a real, if modest, gain.

Three refinements that change the answer:

• Volume you were going to trade anyway is free. If you already turn over $500,000 a month and are moving venues regardless, the requirement costs you nothing incremental. This is the only situation in which a large volume requirement is harmless, and it is the situation the terms are not written for.
• Leverage inflates notional cheaply on perps. A requirement expressed in notional is easier to clear on a leveraged perp than on spot — which is exactly why some venues express it in fees paid instead.
• The deadline compresses everything. A $500,000 requirement over ninety days is a different instrument from the same requirement over seven.

4. Payout asset: what you actually receive

Read this clause before any other. "$200" can mean at least four different things:

That last row is the one that catches people. Bonus margin is not a bonus, it is leverage. You can trade with it, and often you can withdraw the profits it generates, but the principal is never yours. Losses hit your real balance first in some implementations and the bonus first in others — that detail alone can double or halve the value, and it is always somewhere in the terms.

Native-token bonuses are a position, not a payment. If the token is illiquid or locked, mark it down accordingly and be honest that you are being paid in a leveraged bet on the venue.

5. Expiry: three separate clocks

Bonuses carry up to three deadlines, and they are not the same:

• Offer window. When the promotion itself is available. Miss it and none of the rest applies.
• Qualification period. How long you have from signing up or depositing to meet the requirements. This is the clock that turns a reasonable volume requirement into an unreasonable one.
• Claim deadline. How long after qualifying you have to actually claim. Programs that require an explicit claim step routinely see people qualify and then forget, and the deadline is enforced.

There is a fourth, softer one worth checking: how long the bonus itself remains valid once credited. A fee credit that expires in thirty days is worth what you can use in thirty days.

The other clauses that matter

• Caps. Total claims across all users and claims per user. A first-come cap means the offer can be exhausted before you finish qualifying — worth checking how many have already been taken.
• Withdrawal restrictions. A bonus that locks your deposit until the requirement is met is a materially different offer from one that only locks the bonus.
• Excluded markets. Volume on the pairs you trade may not count toward the requirement.
• Who pays and how. Some rewards are distributed by the venue directly, some through an on-chain claim, some by manual transfer. It changes the timing and the tax treatment, and it changes who you chase if it does not arrive. The 14 types of trading deals covers the distribution rails.

A five-minute checklist

Before you deposit anything:

1. Am I eligible? New-user definition, referral link required, jurisdiction.
2. What must I do? Deposit minimum, volume requirement, trade count.
3. What does that cost me at my fee rate? Multiply. Subtract from the bonus. If it is negative, stop.
4. What do I receive, in what asset, and can I withdraw it?
5. What are the three clocks? Offer window, qualification period, claim deadline.

If steps 2 and 3 produce a negative number, the correct response is not to negotiate with yourself about it. The bonus is a price, and you have just calculated that it is too high.

The honest framing

A deposit bonus is the venue buying your volume and your account, and it is a perfectly fair trade when the numbers work. The problem is that the headline is designed to be evaluated emotionally and the terms are designed to be evaluated with a spreadsheet, and the gap between those two experiences is the venue's margin.

The bonuses genuinely worth taking share a profile: no volume requirement or a small one, paid in something liquid, available to you at signup through a link you were going to use anyway, and with a claim step you will not forget. That describes a minority of offers, and the minority is where all the value is.

Compare venues on the durable numbers first — fees, depth, funding — using the exchanges comparison, and treat the bonus as what it is: a one-off, claimed once, at signup. More on the wider reward landscape in how to compare crypto exchange rewards.
