Bustabit is the original crash gambling game. Launched in July 2014 as MoneyPot, it invented the rising-multiplier format that Aviator, Stake Crash and every modern crash game later copied. A multiplier climbs from 1.00x and your only job is to cash out before it busts.
If you are new to the wider crash gambling format, Bustabit is where it all began. Everything that followed is a variation on the loop this game shipped first.
The 30-second version
Bustabit is the longest-running crash game, built by Canadian developer Eric Springer in 2014 and still live in 2026. It runs a fixed 1% house edge (99% RTP), pioneered provably fair crash betting with a Bitcoin-block-salted hash chain, and uniquely lets players invest in its bankroll to earn the house edge. It stayed Bitcoin-only and never chased operator distribution, which is exactly why its descendants overtook it.

🏢 Who built Bustabit, and who runs it now
Bustabit was created by Canadian developer Eric Springer, who launched it as MoneyPot on the BitcoinTalk forum on 25 July 2014, making him the verifiable inventor of the crash gambling format. He introduced it as a social Bitcoin gambling game built on a concept he had come up with himself, and reportedly seeded the bankroll with around 77 BTC of his own Bitcoin.
MoneyPot was not a separate predecessor that ran alongside Bustabit. It was the same game, later renamed: opened as MoneyPot in July 2014, sold to a new owner that October, then rebranded Bustabit in April 2015. The ownership has passed twice since.
Jul
MoneyPot, by Eric Springer (espringe)
The original crash game launches on BitcoinTalk. By September 2014 it had logged over 250,000 plays and roughly 180 BTC wagered across about 1,750 players. This is the birth of the genre.
Apr
Ryan Havar (RHavar) rebrands it Bustabit
Havar buys the game in late 2014, renames it Bustabit in April 2015, introduces bankroll investing and runs the first provably fair seeding event. He later launches the sister dice site Bustadice in 2017.
Feb
Daniel Evans (devans) takes over and ships v2
Evans buys Bustabit from Havar, launches version 2 with a fresh hash chain, removes the old bonus and instant-bust system, and still operates the site today.
🔍 Worth noting
The provably fair scheme was a team effort, not solely Springer’s. In Havar’s own account it was first proposed by Dooglus, the operator of the dice site Just-Dice, refined by Eric, and solidified into code by a developer known as Steve. Springer is the game’s creator; Dooglus originated the hash-chain fairness concept.
⚡ How a Bustabit round works
A Bustabit round is a single shared multiplier that every player in the room rides together. You place one bet, watch the multiplier climb from 1.00x, and cash out before it busts. There is no second betting panel and no per-player curve: the crash point is the same for everyone in that round.
Place one bet
One bet per round, denominated in Bitcoin bits. The minimum is tiny, as low as 1 bit (0.000001 BTC), so stakes scale from trivial to large.
Set an auto cash-out (optional)
A target multiplier sent to the server in advance. It fires even if your client fully disconnects, which is the recommended safety setting on an unreliable connection.
Watch the multiplier climb
It rises in real time from 1.00x. Every player sees the same curve and each other’s cash-outs in a shared multiplayer feed, with rounds running anywhere from roughly 1 to 60 seconds.
Cash out, or bust
Bank your stake times the multiplier at any moment, or lose the bet if the round busts first. A bankroll-protection cap can also force everyone out, covered in the features section below.
📊 RTP and house edge
Bustabit runs a fixed 1% house edge, a 99% RTP, which is one of the lowest edges anywhere in the crash genre. The current version 2 bakes the margin directly into its crash formula, crashPoint = floor(99 / (1 - X)) / 100, where using 99 instead of 100 is precisely the 1% cut. The result is an average multiplier near 1.98x.
That margin places Bustabit firmly in the lowest tier of the genre. We rank the cheapest crash games to play in our guide to the best low house edge crash games.
🔍 Worth noting
The original version 1 worked differently. It scaled its margin between 0% and 1% depending on how long you held, plus a 1-in-101 instant bust at 0.00x that funded a bonus pool, so random play could face an effective return as poor as minus 2%. Version 2 removed those mechanics and put the clean edge in the formula instead. Some 2026 reviews quote 98.82% for v2; that is a measurement reading, not a different edge. The operative figures are 99% and 1%.
Like every crash game, your expected return is the RTP at every cash-out target: 99 pence back for every pound staked, no matter where you aim. We prove why no target beats the edge in the crash gambling maths guide. The probability of reaching any multiplier is simply the RTP divided by that multiplier.
“Aim for 2x or aim for 100x, it makes no difference: you get 99 pence back on the pound either way.”
⚙️ Features that set Bustabit apart
Bustabit’s defining feature is something no descendant copied: players can invest in its bankroll and earn the house edge, effectively becoming the casino. Alongside that sit a scripting engine, a hard bankroll-protection cap and a deliberately Bitcoin-native, anonymous design.
💡 Key insight
Investing in the bankroll is a positive-expectation bet with brutal variance, not a savings account. You earn that edge over the long run, but Havar himself logged an 800 BTC swing in a couple of days. Treat it as a bet with good odds rather than a yield product.
📝 For the record: Sponsored 2026 press releases claim Bustabit has added Ethereum and Lightning support. These appear only in PR content and are unverified, so treat Bustabit as Bitcoin-only until the site itself confirms otherwise.
🔢 Multiplier distribution
Because Bustabit is effectively uncapped on the multiplier but capped on profit, its distribution is the familiar crash shape: most rounds bust low, and a small fraction run very high. The multiplier can mathematically reach into the quadrillions, but the chance of approaching that is vanishingly small, and the max-profit cap binds long before then.
Flip the reach probabilities around and you get the bust picture, which is the more honest way to read the game: how often a round ends before you would have banked a given target.
The bottom line: Roughly half of all rounds bust before 2x. Chasing big multipliers means accepting that you will lose most rounds to bank a rare large one, and the edge applies whatever you aim for.
🛡️ Fairness: three generations of provably fair
Bustabit did not just adopt provably fair, it invented provably fair crash gambling, and has re-seeded its system across three distinct generations since 2015. If the cryptography is new to you, our provably fair explained guide covers the general concept. Bustabit’s own implementation is the model the rest of the genre inherited.
The design is a pre-committed chain of SHA-256 hashes, generated by repeatedly hashing a secret server seed back into itself, then consumed in reverse so the first game uses the last hash. The chain is salted with the hash of a future, then-unmined Bitcoin block, which proves the operator could not have hand-picked a sequence unfavourable to players. Each new owner has re-run that ceremony.
The version 2 codebase moved closed-source after a hot-wallet exploit in which an attacker found a way to read a round’s outcome early and drained 122.5686 BTC. The bug was patched, and the third generation in 2024 added a multi-party verification layer built around ActuallyFair’s third-party verifier and a BLS public key. Here is how a player checks any round.
Record your round data
After a round settles, note its server seed, your client seed and the nonce.
Confirm it sits in the chain
Hash the server seed and check it produces the hash previously published for that game. Because the chain runs in reverse, a past result can never be altered without breaking every hash after it.
Reproduce the crash point
Run the values through Bustabit’s open-source verifier, or one of the independent JavaScript and Rust verifiers, to recompute the exact result yourself.
Tie it to the Bitcoin block
Cross-check the chain’s terminating hash against its Bitcoin block salt. Because the block was unmined when the chain was built, the operator could not have rigged the sequence in advance.

🏆 How Bustabit compares to modern crash games
Bustabit beats its descendants on house edge and transparency, but loses on everything that drives mass adoption: fiat support, mobile polish and distribution. The games that copied its format, including Aviator and Stake Crash, won by inverting the choices Bustabit made.
In short, Bustabit’s creator built for honesty and was out-competed on distribution by the very format he invented. Spribe’s own chief executive has publicly acknowledged that his team did not invent the genre.
“Bustabit’s creator built for honesty and was out-competed on distribution by the very format he invented.”
The format Bustabit pioneered now powers some of the fastest, most heavily marketed gambling products online, and the speed and accessibility behind that growth carry real risks. We cover the research evidence, the risk factors and what regulators are doing in a dedicated guide: crash gambling and player harm.
💡 Common mistakes and practical tips
The biggest mistake with Bustabit is treating bankroll investing as a safe yield, when it is a high-variance bet that can swing hundreds of Bitcoin in days. A few practical points keep the rest of the experience clean.
- Do not treat investing as savings. The expectation is positive but the variance is extreme. Never invest money you cannot watch swing hard in either direction.
- Use server-side auto cash-out. It fires even if your client disconnects, which matters on an unreliable connection where a manual cash-out could be missed.
- Ignore any predictor tool. The crash point is sealed by the hash chain before betting opens, so prediction is mathematically impossible. The wider scam ecosystem is covered in our crash game predictor scams guide.
- Check the jurisdiction rules. Bustabit blocks Costa Rica and US users, among others, and it holds no recognised gambling licence.
📝 For the record: Bustabit operates as a crypto-native site without a recognised gambling licence. Corporate filings are inconsistent across sources, naming both Green Train S.R.L. (Costa Rica) and Apis N.V. (Curacao), so treat the corporate ownership as unconfirmed.
❓ Frequently asked questions
The questions players ask most about Bustabit cluster around who built it, whether it is fair, and whether the bankroll-investing model is worth using.
Who created Bustabit?
Eric Springer, under the handle espringe, created it as MoneyPot and announced it on BitcoinTalk on 25 July 2014. Ryan Havar bought it and rebranded it Bustabit in April 2015, and Daniel Evans has owned and operated it since February 2018.
Is Bustabit really the original crash game?
Yes. It is the verifiable first game of the rising-multiplier crash format. Aviator, Stake Crash, JetX and the rest of the genre all descend from the format and the provably fair hash chain it pioneered.
What is Bustabit’s RTP?
99%, a fixed 1% house edge, one of the lowest in the genre. The edge is baked into the version 2 crash formula, which divides by 99 rather than 100.
Is Bustabit provably fair?
Yes, and it pioneered provably fair crash gambling. It uses a pre-committed SHA-256 hash chain salted with a future Bitcoin block hash, re-seeded across three generations in 2015, 2018 and 2024, with an open-source verifier players can use to check any round.
Can you make money investing in the Bustabit bankroll?
You earn a proportional share of the 1% house edge, which carries a positive long-run expectation, but the short-term variance is severe. Bustabit takes a 60% commission on profit above the previous all-time high. Treat it as a bet with good odds, not a savings product.
Does Bustabit accept fiat, or only Bitcoin?
Historically Bitcoin-only. Sponsored 2026 announcements claim added Ethereum and Lightning support, but those appear only in PR content and are unverified, so Bitcoin remains the safe assumption until the site confirms otherwise.
