On a 0.05 BTC swap measured through SwapZilla on 2026-05-07, ChangeNOW finished in a median of 11 minutes with a 0.85% spread off mid-market; SimpleSwap took 15 minutes at 1.05%. On the same lane, that 4-minute and 20-basis-point gap is the entire story — until your amount crosses $250k or your destination needs anything other than mainnet BTC. This pairwise comparison walks the four metrics the aggregator measures, calls the winner for each, and flags the cases where the loser is actually the right pick.
TL;DR — who wins for what
| Use case | Winner | Why |
|---|---|---|
| Fastest BTC swap | ChangeNOW | 11 min vs 15 min median end-to-end |
| Cheapest BTC swap | ChangeNOW | 0.85% vs 1.05% spread off mid-market |
| Most discreet onboarding | SimpleSwap | Slightly quieter quote flow on retail tickets |
| Large amounts (>$250k) | SimpleSwap | Lower ceiling but steadier handling in the bracket |
Both providers route through SwapZilla’s /v1/quotes aggregator, so the numbers below are observed routing data rather than marketing-published claims. Neither requires an account to receive a quote.
The two brands in 90 seconds
ChangeNOW launched in 2017 as an instant-exchange aggregator that aimed at one-click swaps without registration. The model is custodial during the swap window — the deposit lands at a ChangeNOW liquidity address, the output is sent to the destination wallet — but no user account exists between swaps. Strengths: speed, Lightning Network support on BTC, broad asset coverage. The published support docs note an automated AML review can trigger above roughly €2,000 equivalent.
SimpleSwap launched in 2018 in the same instant-exchange category. It positions on simplicity and breadth — the coin list sits in the hundreds — and publishes a floating-rate markup around 1.21% and a fixed-rate markup around 2.02% as provider-stated figures. On BTC specifically, our aggregator-observed spread is tighter than the published number because the BTC lane is the most competitive across the integration. No account is required to start.
Speed: 11 min vs 15 min on BTC
The avgTimeMin metric is the median time from “deposit seen on-chain” to “output confirmed at the destination” — it strips out user-side delays like address paste and confirmation clicks. On the BTC source leg:
- ChangeNOW: 11 minutes median
- SimpleSwap: 15 minutes median
Where do the 4 minutes go? Bitcoin confirmation latency is identical for both — neither provider can speed up a 10-minute block. The gap shows up in two places: the internal routing window between deposit-confirmed and output-broadcast (provider-side queue), and the broadcast-to-confirmation lag on the destination leg, which is more aggressive for ChangeNOW because of higher fee bidding on outgoing transactions. SimpleSwap’s fee strategy is closer to economy-tier, which costs minutes on a busy mempool. See how the routing works for the full lifecycle.
For BTC, ChangeNOW edges out on speed and spread; SimpleSwap edges out on quiet large-amount handling. The right pick is the one your specific swap rewards.
Rate spread: 0.85% vs 1.05%
“Spread” in aggregator language is the percentage deviation from a mid-market reference at the moment of the quote. It is what you actually pay, hidden inside the rate, regardless of whether the provider advertises “no fees” (both do, both have spread). On floating rate, BTC source leg:
- ChangeNOW: 0.85% spread
- SimpleSwap: 1.05% spread
On a $5,000 swap, the 20-basis-point gap is $10. On a $100,000 swap, it is $200. SimpleSwap’s own published markup is higher (~1.21% floating); the 1.05% we measure is the BTC lane specifically — the most price-competitive corridor. Floating beats fixed on both providers for BTC because Bitcoin’s 10-to-60-minute confirmation window often outlasts the protection a 30-minute fixed rate offers anyway. For live multi-provider BTC rates side by side, run a quote on SwapZilla — we route through both ChangeNOW and SimpleSwap (plus others) and show the winner per swap.
Limits and large amounts
Both providers accept a $30-equivalent floor on BTC. The ceiling is where they diverge — and where the marketing copy stops being useful.
- ChangeNOW ceiling: ~$1,000,000 per swap (aggregator-observed)
- SimpleSwap ceiling: ~$750,000 per swap (aggregator-observed)
The honest framing: at any meaningful size, both providers route through enhanced compliance. The published “no sign-up” model is real for retail swaps in the four-figure band; above roughly $10k–$15k either provider may request additional information regardless of the headline policy. For genuinely seven-figure moves, expect a conversation with a compliance contact and a slower settlement window. For mid-bracket large amounts — $50k–$250k — SimpleSwap’s quieter retail handling tends to draw fewer manual escalations than ChangeNOW’s tighter automated triggers. If you’re offloading BTC into stablecoins, see the BTC to USDT TRC20 lane for the common destination.
Networks: Lightning is the only structural difference
Every other metric is a delta on the same dimension. Network coverage is a flag — either it’s there or it isn’t.
- ChangeNOW:
bitcoin(mainnet) +lightning - SimpleSwap:
bitcoin(mainnet) only
If you want to send small BTC amounts quickly — under $200 where on-chain fees and 10-minute blocks feel disproportionate — Lightning is the deciding factor and ChangeNOW wins automatically. For mid-size and larger swaps, mainnet is the realistic settlement layer for both providers and the network field is a tie. Privacy users routing toward BTC → XMR will use mainnet either way because XMR doesn’t have a Lightning equivalent.
Account, refunds, and what happens when a swap stalls
Neither provider asks for an account or email to start. The friction shows up in two places that matter more than the sign-up screen.
Refund address. Both providers accept a refund address when you create the order. If the deposit window expires or the swap fails, the deposit goes back there minus network fees. Always supply one you control. Through SwapZilla the field is mandatory on every order — that pattern carries through to the underlying provider.
Stalled-swap handling. Terminal statuses are similar: TIME_EXPIRED if the deposit doesn’t arrive in the window, FAILED for routing problems mid-flight. Response on the human side is where ChangeNOW edges out — same-day escalation through their support channel. SimpleSwap’s ticket queue is slower in the 24–72 hour band but the refund mechanic itself is identical.
Both providers say “no account required.” Both also have enhanced-check thresholds that activate around the same dollar amount. The honest comparison isn’t account-vs-no-account — it’s where each one’s friction shows up.
Verdict by use case
Fastest pick — ChangeNOW. 11 minutes vs 15 minutes is the whole pitch, and the Lightning option compresses small BTC swaps further.
Cheapest pick — ChangeNOW. 20 basis points tighter on the same lane is real money on anything above a few thousand dollars.
Mainstream BTC → XMR privacy hop — ChangeNOW by default. Speed + spread wins, and XMR doesn’t need Lightning so the network advantage carries cleanly into the privacy use case. Compare with the dedicated BTC to XMR route.
$100k+ moves — SimpleSwap. Lower automated-review pressure in the bracket, slightly lower ceiling but the bracket-fit matters more than the headline ceiling.
The lazy way to make the call: open the swap widget, paste the pair, watch both quotes stream in side by side. The aggregator picks the right one for the specific amount and rate type. No account.
Methodology
Numbers in this comparison are not provider-published claims. They come from SwapZilla’s own routing telemetry on the BTC source leg.
- Data source: SwapZilla aggregator data, snapshot dated 2026-05-07 (
STATS_LAST_UPDATEDin our provider stats). - Sample lane: BTC → BTC-equivalent representative basket; metrics are the BTC-row aggregates across requests routed through each provider during the snapshot window.
- Metrics defined:
avgTimeMin— median end-to-end execution time in minutes, from deposit-seen to destination-confirmed.rateSpread— percentage deviation from mid-market reference at the moment of quote.minSwapUsd/maxSwapUsd— floor and ceiling the provider’s API accepted on a BTC source leg without escalating to enhanced verification.requiresAccount— whether a user account is required to receive a quote (both: false).supportedNetworks— network options the provider exposed for the BTC leg.
- Limitations: numbers reflect routing observed through SwapZilla and may differ from each provider’s own dashboard. Larger amounts (above roughly $10–15k) may still trigger manual review on either side regardless of the published policy. We re-snapshot quarterly; see
dataFreshDatefor the freshness of this comparison. - Affiliation: SwapZilla aggregates both providers’ quotes and earns a spread on routed volume. Neither brand receives preferential placement. The winners above are determined purely by the snapshot data.
