We wanted this BetKarma exchange review to start from a real swap, so we ran one. On 19 October 2026, we sent 0.00291303 BTC (about $239) and got 236.72 USDT back roughly 22 minutes after opening the order.
LandOfCrypto review score
BetKarma is a custodial exchange and mixer with no sign-up and no email. You paste in a wallet address, send coins to the deposit address it gives you, and wait. It’s about as simple as a crypto swap gets, and that’s also the catch. You’re trusting the service with your coins for a while, so the small print deserves a closer look than usual.
The price was the surprise. The order said 0.8%. What we actually paid worked out closer to 1.15%. Our LandOfCrypto Rating for the exchange route lands at 6.5/10, and the sections below show how we got there.

What BetKarma is
BetKarma does two things. It swaps one coin for another, and it mixes, which means sending you the same asset back (BTC for BTC, ETH for ETH, USDT for USDT).
You can see BetKarma exchange full attribute breakdown, including KYC tier, liquidity model, and supported coins, in our instant exchange directory listing.
Swaps don’t need an account. Whichever browser creates the order gets private access to that order’s page. From any other browser, you’d need the order ID and the exact recipient address.
Each order page sets its own ground rules: a deposit address, an accepted amount range and a deadline. Cross-asset deposit addresses stay valid for 15 minutes. Mixer addresses get a full hour.
How an order runs
- Pick a pair and paste the recipient address.
- The order page shows a deposit address, an accepted range and a deadline.
- Send one transaction before the deadline.
- The service waits for the required confirmations.
- The payout arrives, usually within 1 to 90 minutes. The terms allow up to 3 extra hours in exceptional cases.
BetKarma
Coins, confirmations and limits
The home page talks about 14 assets. The order rules name BTC, LTC, ETH and ERC-20 tokens, TRON, Solana, BNB Smart Chain, Monero and shielded Zcash, and our session also pulled in icons for DAI, LINK and XRP.
According to the terms, any supported asset can be swapped for any other. Minimums and maximums aren’t published as a list, though. You see them in the swap form and on the order page for each pair.
Confirmation counts differ a lot between networks. They decide how long you wait before the rate locks and the payout can start.
Confirmations required before payout
| Network | Confirmations |
|---|---|
| Bitcoin | 2 |
| Litecoin | 2 |
| TRON | 1 |
| Solana | 1 |
| Ethereum and ERC-20 | 6 |
| BNB Smart Chain | 15 |
| Monero | 10 |
| Zcash (shielded) | 4 |
Two more rules are worth a glance. A payment has to be visible on the network before the deadline, or it isn’t credited automatically. If you send more than the maximum, only the maximum is exchanged, and the rest goes to support to sort out.
Fees and how the rate works
Fees are where this BetKarma exchange review gets interesting. There’s no separate payout line. The fee is baked into the rate, and every direction has its own percentage.
Timing matters more than the percentage, though. On cross-asset swaps, the rate floats until your deposit reaches the required confirmations, and only then does it lock. The fee shown at booking applies to whatever amount was actually received.
That makes the figure on the order page an opening estimate, nothing more.
There’s also a small mismatch on the home page, where the swap form says “Fixed rate, fee included”. Our BTC-to-USDT order was floating, and the Letter of Guarantee said so in plain terms.
Fee and rate rules
| Item | Rule |
|---|---|
| Fee shown on our order | 0.8% (BTC to USDT, ERC-20) |
| Cross-asset swaps | Floating until the deposit is confirmed |
| Mixer and Zcash orders | Rate and amounts locked at creation |
| Fixed cross-asset orders | A move above 1% before detection may mean a refund or new terms |
| Network fees | Paid by the sender |
| Public cross-rates | CoinGecko and Kraken figures are indicative and exclude spread and fees |
Our test: BTC to USDT in about 22 minutes
Everything in this part rests on a single order, so it shows how the service behaved once, not how it always behaves. We swapped BTC for USDT on the ERC-20 network, about $239 worth.
The Bitcoin transaction (4cd6dd7e215b0be8f450ba27f06c3e43408cc0f9a3edf1d88d329749ece1b35c) had one output, 291,303 sats, going to the deposit address. The sender paid a 225-sat network fee.
Timeline of the order
| Step | Time (UTC, 19 Oct 2026) | What we saw |
|---|---|---|
| Order created | 14:44:55 | Floating rate, 0.8% fee, 15-minute deposit window |
| First confirmation | 14:51:32 | Block 972171 |
| Second confirmation | about 15:02:17 | Block 972172. The rate locks here |
| Payout sent | 15:07:11 | Ethereum block 26,227,412. One transfer of 236.72 USDT |
| Last status check in our browser | 15:07:38 | Order page stopped polling |
The gap between the two confirmations was the longest stretch. Bitcoin blocks arrive at uneven intervals, and this one took about 11 minutes.
The USDT showed up as a single transfer (0x6d6ae85878a0166f94443a2ea5254fd3039e3e8e947ebf9dea69ec438b11f41d) about five minutes after the rate locked. It was exactly 236.72 USDT, sent to our address, with the sending side covering gas of roughly 0.0000507 ETH.
What it cost
To estimate the real fee, we compared the payout with the Binance BTCUSDT one-minute candle for 15:02 UTC (open 82,210.01, low 82,202.00, high 82,276.67). BetKarma doesn’t show its own reference price, so treat this as an estimate.
| Measure | USDT |
|---|---|
| BTC value at the candle open | 239.48 |
| Expected payout with a 0.8% fee | 237.56 |
| Received | 236.72 |
| Gap | 0.84 |
That puts the effective cost near 1.15%, or anywhere from 1.14% to 1.23% depending on where in the candle the lock happened. The order doesn’t break the gap down. A wider spread in the floating rate would explain it, and so could a payout cost.
On a $239 swap, the gap is under a dollar. If the same gap held at $10,000, it would be about $35, but we only tested the small amount.
The Letter of Guarantee
Every order comes with a Letter of Guarantee, a plain text file with the order terms signed by a Bitcoin key. The signing address BetKarma publishes is bc1q6etkarmarvej0874ghw396eacejlsy5ygew5yk.
Ours (order 9kkzay78j71dz6) listed the direction, the 0.8% fee, the floating-rate model, the deposit address, the recipient and an expiry of 14:59:55 UTC. The signature and the signer’s address came attached.
Floating orders get two versions. The first fixes how the deposit will be priced, not the number itself. Ours listed a booking snapshot of BTC at $81,933 and USDT at $0.9992. By the time the rate locked, Bitcoin was higher, so that first letter could never have predicted our payout.
Letter versions
| Order type | Versions | What is recorded |
|---|---|---|
| Floating (all cross-asset swaps) | Two | Before the lock: range, fee, pricing rule. After the lock: locked rate, amounts, exact lock time |
| Fixed (mixer and Zcash deposits) | One | Rate, exact deposit and payout amounts, fee, deadline |
A signature can be checked in an online verifier, or by hand in Electrum, Sparrow Wallet or Bitcoin Core (verifymessage).
What that check proves is narrower than it sounds. A valid signature shows the text came from whoever holds the key. It says nothing about whether the payout will happen, and the letter records terms only, never the live status of an order.
Custody and security deposits
BetKarma is custodial. Between your deposit and your payout, your coins sit with the service, so you’re trusting it across two separate blockchain transactions.
The payout isn’t your deposit forwarded on. BetKarma says payouts come from an internal reserve, which may be topped up through centralised or decentralised exchanges. One payout can even arrive as several transactions that add up to what you’re owed.
Our order lines up with that. The USDT came from an address Blockscout tags as NEAR Intents, a cross-chain swap route, not from a wallet we could tie to BetKarma. Our BTC deposit stayed unspent through the payout. About 2 hours 42 minutes later (block 972185), it was merged with six other inputs in one consolidation transaction (42fab4bbe548e400e3c19011761b627111210765e208a660225a2e74dac2f57c), which paid 12,508,837 sats to a single address.
The reserves themselves aren’t published, so we couldn’t check them against the wallets.
To back all this up, the site shows about $66K in security deposits, valued on 19 October 2026. The pieces do add up:
Listed security deposits
| Placed with | Amount |
|---|---|
| AltcoinsTalks | 0.32 BTC (about $26K at roughly $82K per BTC) |
| KycNotList | $20K |
| AntiSwap | $10K |
| OrangeFren | $10K |
What’s missing is more telling. The page doesn’t say who holds the funds in each case, and it doesn’t explain how a customer would claim against a deposit.
The operator isn’t named either. There’s no legal entity, jurisdiction or address, and the terms define no formal dispute process. Disputes go through support, with the Letter of Guarantee as the main reference.
Privacy: what we saw and what we can’t see
We recorded our browser session while placing the order. All 528 requests went to betkarma.art. Nothing went to Google Analytics, Meta or any other outside tracker, and all 33 JavaScript files came from the same domain.
The site does run a tracker of its own. Two requests hit an internal analytics endpoint and sent the page path, a referrer field and a source field. The last two were empty in our session.
Cloudflare sits in front of the site and proxies the traffic.
Privacy claims and what backs them
| Claim | What we found |
|---|---|
| No KYC | The terms say the service never requests identity documents |
| No AML screening | The FAQ says it runs no screening or blockchain analytics |
| No logs | Appears in the page description only. The terms have no logging policy |
| Order removal | After completion or expiry, an order can be removed from public history. Minimal service data is kept for internal records |
A browser recording only shows what leaves your browser. It can’t show what the server keeps. The service can see your IP address, request times and order details, and it doesn’t say how long it holds on to them.
Extra tools: risk check, Tor and SimpleX
Beyond the swap form, there are three add-ons, and each comes with a catch.
Add-on tools
| Tool | What it does | Limits |
|---|---|---|
| Coins checker (payout risk check) | Runs a multi-hop fund-flow check on an address using MistTrack by SlowMist. Flags sanctioned entities, mixers, gambling, hacks and phishing | Only after a completed order. Free, a few checks per order. Does not cover Monero or shielded Zcash |
| Tor version | Text-only terminal with no JavaScript, images, cookies or accounts | Works through a saved private order URL |
| SimpleX route | Operator-assisted, end-to-end encrypted chat. Terms and a signed guarantee are agreed before paying | No public fees or limits. |
The risk check suits the receiving end. If your coins come out of a mixing service, it shows how the address looks to an analytics tool. The page itself calls the result informational and admits other providers may rate the same address differently.
Terms that matter when something goes wrong
Most swaps will go through without a hitch. The terms only matter on the day one doesn’t, and when that day comes, most of the risk sits with the sender.
Take a common slip: USDT sent on the wrong network. The terms call that a sender mistake. A refund isn’t guaranteed, and if one does happen, the network fee comes out of the refunded amount.
Terms at a glance
| Situation | What the terms say |
|---|---|
| Wrong network or address | Refund not guaranteed. Network fee deducted if refunded |
| Late payment | Not credited automatically. Contact support with the order ID |
| Underpayment | Payout recalculated proportionally. Below the minimum, a refund needs your agreement |
| Overpayment | A surplus under about $1 stays with BetKarma |
| Payout delay | Should start within the stated estimate and can exceed it by up to 3 hours |
| Disputes | Handled by support. No formal procedure. The Letter of Guarantee is the main reference |
| Governing law | None stated |
| Eligibility | 18 or the age of majority. Users check their own local rules |
| Casino cashback | 100% of the service fee credited as a casino bonus with a 50x wagering requirement |
Who BetKarma fits
This BetKarma exchange review points at a fairly narrow audience: people who already live in crypto. The service swaps coins for coins and nothing else. We saw no card or bank payment option, and there’s no account to fall back on.
It suits someone holding BTC who wants Monero, or someone with USDT on TRON who needs BTC. They already have a wallet, know their networks and don’t panic while waiting on confirmations.
A first-time buyer is a different story. Nothing here can undo a transfer, so a wrong network means a lost payment, not a support ticket.
Know-how the service assumes
| You should be comfortable with | Why it matters here |
|---|---|
| Your own wallet and recipient address | The payout goes to the address you paste. There is no recovery |
| Choosing the right network (ERC-20, TRON, BSC) | A wrong network is treated as a sender mistake |
| Confirmations and deadlines | A payment that misses the deposit window is not credited automatically |
| Floating rates | The final amount is known only after the rate locks |
| Custodial trust | Your coins sit with the service between two transactions |
One last thing. BetKarma says it does no KYC and no AML screening, and it leaves legal compliance to the user. Rules for privacy services differ from country to country, so it’s worth checking yours before sending anything.
Is BetKarma custodial?
Yes. Your deposit goes to BetKarma, and the payout comes from its own reserve rather than your original coins. You’re trusting the service across both transactions.
Does BetKarma require KYC?
The terms say it has never asked for identity documents, and the FAQ says it runs no AML screening. What you do with that is up to you, since users stay responsible for the rules where they live.
How long did our swap take?
About 22 minutes from opening the order to the USDT payout. Bitcoin needs two confirmations, so a lot of that depends on block timing, and the terms allow a payout delay of up to 3 extra hours.
What is the real fee?
The order said 0.8%. Measured against the Binance BTCUSDT candle at lock time, we paid about 1.15%. With a floating rate, the final figure depends on where the lock lands.
Is BetKarma safe to use?
Our BetKarma exchange review covers one completed order, and it went through as described. Safety still comes down to trusting an operator nobody can name, which is why many people start small.
What happens if a payment is late or on the wrong network?
A late payment isn’t credited automatically, so you’d contact support with the order ID. A wrong-network payment counts as a sender mistake, and a refund isn’t guaranteed.
