One Coin, 1 or 150 Confirmations: What Exchange Deposit Rules Cost You
Four exchanges, one asset, four different confirmation counts - Monero credits at 5, 32 and 150 depending on where you deposit. We pulled each number from the platform's own endpoint and measured what it costs in minutes against 600 live blocks per chain.
Same asset, same day, four exchanges, four different answers. On 4 November 2026 HitBTC's public currency endpoint asked for 5 confirmations before crediting a Monero deposit; WhiteBIT's asset endpoint asked 32; KuCoin's currency list asked 150. On Bitcoin the spread runs the other way, from 1 confirmation at HitBTC to 3 at KuCoin and Kraken - and Kraken's own help page tells readers that those 3 confirmations take "approximately 45 minutes." A confirmation count is not a property of the coin. It is a property of the platform's risk model, and what it charges you is time. We took each number from the exchange's own machine-readable endpoint, then measured what it means in minutes against 600 live blocks per chain. (Monero confirmation waits)
The published numbers, as of 18:00 UTC today. Bitcoin: 1 confirmation at HitBTC, 2 at WhiteBIT, 3 at KuCoin and Kraken. Monero: 5 at HitBTC, 32 at WhiteBIT, 150 at KuCoin. Litecoin: 5 / 18 / 18. Dogecoin: 5 / 36 / 36. Dash: 3 / 25 / 30. Bitcoin Cash: 2 / 6 / 6. Zcash: 3 / 35 / 120. USDT on Tron: 3 / 20 / 3. Three of these numbers came out of JSON endpoints, so they are the same values the exchange's own deposit screens use. The fourth, Kraken's Bitcoin, comes from its support article, which also explains the logic: funds are not credited until a set number of confirmations to avoid double-spend risk. That is the only rationale any of the four publishes. (BCH to XMR guide)
Why the same coin gets a 30-fold difference. Three things move the number, and only one is about chain security. The first is loss at that depth: a 1-confirmation Bitcoin credit is cheap insurance if the per-block exposure is small and expensive if a single deposit can be large, which is why a venue willing to take a large deposit publishes a bigger number. The second is capital: every confirmation is time the platform has taken your coins and credited nothing, and that inventory has a price. The third is support load - a deposit that sits at 149 of 150 generates a ticket, and a ticket costs more than the risk it prevents. None of the four documents which of these dominates. Security alone cannot explain a 30-fold spread: on a two-minute chain, 150 confirmations is nearly five hours, far past the point where reorg risk on Monero is a live concern.

Turning confirmations into minutes. We pulled the last 600 blocks of each chain - Bitcoin and Litecoin from their Esplora endpoints, Dogecoin from Blockchair's block index, Monero from a public node's header range - sorted them by height, and computed the wall-clock time from a transaction's inclusion block to the Nth block after it. N confirmations means N-1 further blocks, so the wait is a sum of consecutive intervals, not a multiple of one average. Bitcoin's sample covers 614 blocks (973,945 to 974,558) and 106.5 hours; Litecoin 614 blocks over 25.3 hours; Dogecoin 600 blocks over 10.7 hours; Monero 600 blocks over 19.3 hours. Median inter-block intervals in those windows were 7.8 minutes for Bitcoin, 1.9 for Litecoin, 42 seconds for Dogecoin and 74 seconds for Monero. (Monero confirmation waits)
What each published rule actually costs. Bitcoin at 3 confirmations, the KuCoin and Kraken rule: 18.1 minutes at the median, 39.6 at the 90th percentile, 63.8 at the 99th, worst case 86.5 minutes in our window. Bitcoin at 6 confirmations: 50.8 / 80.0 / 110.3 minutes. Monero at 5 (HitBTC): 7.1 minutes median. Monero at 32 (WhiteBIT): 59.1 minutes median, 89.2 at the 99th. Monero at 150 (KuCoin): 282.1 minutes median, 313.2 at the 90th, 334.9 at the 99th - four hours forty-two minutes as the normal case, five and a half hours at the tail. Litecoin at 18: 42.2 minutes median. Dogecoin at 36: 37.6 minutes median. The same deposit, routed to a different venue, is a coffee break or an afternoon. (how Monero fees work)
Kraken's "45 minutes" is an envelope, not a schedule. Its page says a Bitcoin block arrives on average every 15 minutes and that three confirmations take about 45 minutes; we measured 18.1 minutes at the median and 39.6 at the 90th percentile, so the published figure sits near the 90th percentile of what actually happens - it describes a bad day, not a typical one. That is how to read any exchange's number: a promise written wide to avoid complaints, over a skewed distribution. In our Bitcoin window the mean block gap was 10.4 minutes but the median 7.8, and 36 of 613 gaps exceeded 30 minutes. The variance is the part nobody publishes. Two Bitcoin confirmations have a coefficient of variation of 0.97 - the wait is as variable as its own average; three, 0.67; six, 0.41. Monero at 5 is 0.51, at 10 is 0.33, and at 150 it is 0.08, a standard deviation of 22.6 minutes around a 283.8-minute mean. Dogecoin at 36 is 0.11. Few confirmations are fast; many are predictable, and the law of large numbers helps in the least convenient way: the venue demanding 150 confirmations makes you wait hours and then returns almost exactly those hours, while the 1-confirmation venue occasionally hands you a 56-minute block. For a same-day route, the high-count venue is the one you can schedule around. (Monero confirmation waits)
"Credited" has two meanings. KuCoin publishes a second number beside the final count - pre-confirmations - and the gap is where most support tickets are born: 40 of 150 for Monero, 12 of 18 for Litecoin, 12 of 36 for Dogecoin, 1 of 3 for Bitcoin. At the pre-count the balance is tradable but cannot be withdrawn; the final count is when it can leave. Monero piles a protocol floor on top: an incoming output is not spendable until it is 10 blocks deep, a rule enforced by the chain rather than the venue, so even a 1-confirmation Monero credit cannot be moved for roughly another 17 minutes. On top of that, a withdrawal may pass a manual review that no published confirmation number describes. (Monero confirmation waits)
What this means when the exchange is a leg of a swap, not the destination. A swap only needs the provider to see your transaction; it does not need your coins to be credited to an account. That is why a swap deposit is typically live after one confirmation while an exchange deposit at the same moment is still hours away, and why our own order window is 30 minutes with a 120-second quote rather than a block count. The trap is chaining the two without adding the waits: exchange to self-custody to swap to exchange again means one withdrawal queue, one deposit confirmation rule and one payout confirmation rule in series, and the slowest link sets the arrival time. If the final destination is a venue asking 150 Monero confirmations, budget five hours after your swap settles, not five minutes. (Monero confirmation waits)
Practical rules. Estimate with the platform's published count times measured percentiles, not with "ten minutes a block". Read the pre-confirmation number as well as the final one before you plan a same-day route. Do not treat a broadcast transaction as arrived, and do not open a ticket at hour two of a 150-confirmation wait - check the pre-count first. And size the threshold to the amount: one confirmation is a reasonable bet on a small Bitcoin deposit and a poor one on a large one.
