1xBit Review 2026
A bonus capped in bitcoin, at 40x — about $60 of expected cost for every $100 of bonus you take
Reviewed by Dana Reeves, Lead Bonus Analyst · Updated 2026-09-02
Is the 1xBit bonus worth it? A bitcoin-denominated cap makes the headline unquotable in fiat; the per-unit maths is what matters and it is poor At 40x on the bonus, clearing $100 of bonus costs about $160 in house edge — about -$60 for every $100 taken. If wagering applies to deposit + bonus, about -$220. Verify the live terms before depositing.
- Best thing: A 30-day window and one of the widest coin lists in this comparison
- Worst thing: 40x means every $100 of bonus costs about $160 in expected house edge to clear
- Verdict: A bitcoin-denominated cap makes the headline unquotable in fiat; the per-unit maths is what matters and it is poor

Verdict: Bad
The terms, line by line
| Offer | First deposit: 100% match up to 1 BTC |
| Cap | Denominated in BTC, so no fixed fiat figure exists |
| Wagering | 40x |
| Wagering applies to | Not stated in any source we found |
| Cost per $100 of bonus (bonus-only) | About $160 — net about -$60 |
| Cost per $100 of bonus (deposit + bonus) | About $320 — net about -$220 |
| Time limit | 30 days |
| Previously recorded here | 125% up to 1 BTC across 4 deposits at 35x — superseded |
Not confirmed on the operator's own terms page. The figures below come from third-party listings, which we treat as a lead rather than a fact. Our older record described a 125% offer across four deposits at 35x. The research pass recorded the first deposit as 100% at 40x over 30 days, and we have used that. We could not load this operator's own terms page automatically -- it refuses automated requests -- so every figure here comes from third-party listings and none of it is confirmed at source. Treat it as a starting point and read the live terms before you deposit.

How to Use This Bonus Safely
- Find the wagering basis — it moves the cost from about $60 to about $220 per $100 of bonus.
- Confirm whether the live offer is 100% at 40x or the older 125% at 35x.
- Work the cap in the currency you are depositing, not the one a listing quoted.
- Check for a maximum bet clause; our research did not surface one.
- The welcome bonus terms showing the multiplier and cap
- The sentence stating what wagering applies to
- The 30-day expiry clause
- The cashier coin list
Why there is no dollar figure on this page
1xBit caps its welcome bonus at 1 BTC. That is not a fixed amount of money — it is a fixed amount of bitcoin, and what it is worth in dollars or euro depends on the day you read it.
Sites that quote a fiat figure for a BTC-denominated cap are picking a price and presenting it as a term. We will not do that, because next month it will be wrong and there will be no note explaining why. The same applies to mBit, FortuneJack, TrustDice and Cryptorino, all of which cap in BTC.
What can be stated honestly is the ratio, and the ratio is the number that actually decides whether an offer is worth taking. It does not move with the bitcoin price.
The cost per unit of bonus
At 40x applied to the bonus alone, clearing $100 of bonus requires $4,000 of turnover, which costs about $160 in house edge at 96% RTP. You received $100. The expected outcome is about -$60 for every $100 of bonus — and it scales linearly, so a bonus ten times larger loses ten times as much.
If the multiplier applies to deposit plus bonus instead, the base doubles on a 100% match: $8,000 of turnover per $100 of bonus, costing about $320, for an expected -$220 per $100. No source we found states which basis applies.
Either way it is at the poor end of what we have measured. FortuneJack's 30x on bonus funds costs about $20 per $100 of bonus; 1xBit's 40x costs three times that.
Our own record was different, and we changed it
This page previously described the offer as 125% up to 1 BTC spread across four deposits, at 35x. The research pass recorded the first deposit as 100% up to 1 BTC at 40x over 30 days, and we have used that.
We flag the change rather than silently swapping the numbers because a reader who saw the old version deserves to know it moved, and in which direction: the current figure is worse for the player than the one it replaced. Where our sources disagree we keep the less flattering reading, so a bonus never looks better because our information is thin.
Neither version is confirmed on 1xBit's own terms page, which refuses automated requests.
What else is worth knowing
The 30-day window is generous by the standards of this comparison — four times Crashino's seven days and ten times Fairspin's three. Time is the constraint that defeats most bonus attempts, and 1xBit gives you plenty.
The coin list is among the widest here: BTC, ETH, LTC, DOGE, XRP, USDT, ADA and SOL. If you hold something unusual, this is one of the more likely places to be able to deposit it directly. Withdrawals run around four hours.
The 1xBit bonus value breakdown works the same ratio at different deposit sizes, and how bonus EV works explains why the per-unit figure is the one to compare.

Pros & Cons
- A 30-day clearing window, four times what several operators here allow
- One of the widest coin lists in this comparison, including ADA and SOL
- No cashout cap surfaced in our research
- 40x costs about $160 in house edge per $100 of bonus — about -$60 net
- The cap is in BTC, so no fiat figure on any listing is stable
- The wagering basis is unstated, which swings the answer from -$60 to -$220 per $100
BonusOz Verdict
A poor ratio behind an unquotable headline. Capping in bitcoin means every fiat figure you see for this offer is a snapshot someone took on an unstated day, so the only honest measure is the cost per unit of bonus — and at 40x that is about $160 of expected house edge for every $100 of bonus, or roughly -$60 net. The 30-day window and the broad coin list are real advantages. The bonus itself is at the wrong end of the table.
Best for: Players who hold less common coins and want a long window; not those chasing the headline

What to verify before claiming the 1xBit bonus

Current BonusOz data for 1xBit: offer note: 125% up to 1 BTC (4 deposits); wagering: 35x wagering; licence: Curaçao; listed withdrawal speed: around 4 hours; supported crypto: BTC, ETH, LTC, DOGE, XRP, USDT, ADA, SOL. Re-check the live cashier before depositing, especially if your account shows different wagering, max cashout, game contribution, or country terms.
Fast pre-deposit checklist
- Confirm whether wagering applies to the bonus only or deposit plus bonus.

- Look for max-bet, max-cashout, KYC and bonus-abuse clauses before playing.
- Send a small test withdrawal before keeping a larger bankroll on the site.
- Use the BonusOz EV calculator with the exact terms shown in your account.

1xBit — Frequently Asked Questions
How much is the 1xBit welcome bonus worth in dollars?
There is no honest answer, because the cap is 1 BTC rather than a fixed sum. What can be stated is the ratio: at 40x on the bonus, every $100 of bonus costs about $160 in expected house edge to clear, so you expect to be about $60 down per $100 taken.
Is the 1xBit bonus 100% at 40x or 125% at 35x?
Our research recorded the first deposit as 100% up to 1 BTC at 40x over 30 days, superseding an older record of 125% across four deposits at 35x. Neither is confirmed on 1xBit's own terms page, which refuses automated requests. The current figure is the worse of the two for the player.
Does 1xBit apply wagering to the deposit as well as the bonus?
No source we found states it. On the bonus alone the offer costs about $60 per $100 of bonus; on deposit plus bonus about $220. That unstated word is worth more than the difference between most operators' headline offers.
How long do I have to clear the 1xBit bonus?
30 days, which is at the generous end of this comparison — Crashino gives 7 and Fairspin 3. A long window is worth more than it looks, because running out of time is what defeats most bonus attempts.
