Crypto Sportsbooks: How They Work and Why International Books Run on Crypto

By Marcus Chen · 8 min read

If you spent the last decade in U.S. sports betting, the shift looks gradual. Crypto sportsbooks were a fringe option, then a workaround for offshore play, then a real product category. From outside the U.S. — and from inside the founder rooms of the books themselves — the picture is sharper: crypto isn’t a workaround anymore. It’s where international sports betting is being rebuilt.

On a 2024 episode of The Unabated Podcast, host Thomas Viola sat down with Nigel Eccles — co-founder and former CEO of FanDuel, now operating in the crypto sportsbook space. Eccles’ framing cuts through the noise: “None of the books in the U.S. can even take crypto. So that’s how challenging doing crypto in the U.S. is — even the founder of DraftKings can’t take crypto deposits. So we’ve decided to focus internationally.”

That sentence alone reorders how to think about every comparison between “U.S. legal sportsbook” and “crypto sportsbook.” They’re not competing in the same arena.

What Is a Crypto Sportsbook?

A crypto sportsbook is a sports betting operator that accepts cryptocurrency deposits and withdrawals — typically Bitcoin, Ethereum, USDC, or other stablecoins — instead of (or alongside) traditional fiat banking. Most crypto sportsbooks are based offshore relative to the U.S. and serve international markets directly, since U.S. state gaming regulators have not broadly approved crypto as a deposit mechanism for licensed sportsbooks.

In practice, “crypto sportsbook” covers a spectrum:

Crypto-deposit sportsbooks — traditional centralized books that accept crypto as one payment method, like Bet105 and other offshore operators.
Crypto-native sportsbooks — books built on blockchain rails, where settlement, odds, and liquidity all run on-chain.
Crypto betting exchanges — peer-to-peer markets where bettors take both sides of a wager directly, with the platform earning a small fee instead of operator margin.

The differences matter, especially for sharp bettors evaluating where to put real money. The rest of this article walks through the structural reasons crypto sportsbooks exist primarily outside the U.S., and what that means for bettors who care about pricing, limits, and execution.

The Structural Reason Crypto Sportsbooks Live Internationally

The U.S. legal sportsbook market is built around state-by-state regulatory licensing. To accept deposits, a sportsbook needs payment infrastructure that integrates with the U.S. banking system, satisfies KYC/AML requirements, and clears state gaming regulators. Crypto deposits clear none of those gates — the U.S. banking system treats crypto-to-fiat conversions as high-risk transactions, and most state gaming commissions haven’t approved crypto as a deposit mechanism.

The result, as Eccles laid out: even tier-1 U.S. operators can’t accept crypto. That’s not a technology problem — it’s a regulatory one. And it means that anyone who wants to offer crypto-native sports betting at meaningful scale has to either build outside the U.S. regulatory perimeter or operate in the offshore market that already serves U.S. bettors via crypto rails.

This is the part most generic “best crypto sportsbook” content misses. The category isn’t an alternative to FanDuel and DraftKings. It’s a parallel market with completely different operators, regulatory environments, and customer bases.

Insight #1: The Customer Is Different — and That Changes the Product

Eccles’ second observation, also from the Unabated episode, is the one most U.S. betting media won’t write about because it doesn’t fit the “crypto for crypto’s sake” framing: the crypto-native sports bettor is a different demographic than the casual U.S. retail customer, and that demographic shapes the entire product roadmap.

His characterization: “The OG crypto people have come into generational wealth, and now we’re seeing a lot of people speculating within crypto. And within that cohort, there’s a lot of people who are willing to throw around a lot of liquidity.”

In plain English: the crypto sportsbook customer base skews younger, wealthier (often crypto-wealthy), more comfortable with high variance, and more willing to put real size down. That changes what a competitive crypto sportsbook needs to offer:

Higher limits than typical U.S. retail. Crypto bettors aren’t going to be limited at $50 max for showing skill.
Faster deposit/withdrawal flows. Crypto rails clear in minutes; bettors expect that as the baseline.
Original, crypto-native products. Eccles specifically called out the parade of identical crypto casinos using the same third-party providers: “they all use the same third-party products. They’ve got the same crash games, the same slots.” His company chose to build proprietary crypto-native games instead.

For sports specifically, crypto-native means betting exchanges, prediction markets, and peer-to-peer pricing models that don’t require a central book to take the other side.

Insight #2: Crypto Sportsbooks Are Being Built on Crypto-Native Rails — Not Just Bitcoin Deposits

A subtlety the Eccles interview surfaced: there’s a meaningful distinction between a sportsbook that accepts Bitcoin and a sportsbook that’s built on crypto rails. The first is a traditional book with a crypto deposit method. The second is a fundamentally different product.

Eccles’ newer venture is built on Solana — a high-throughput blockchain — as a betting exchange. The architecture means odds, settlement, and liquidity all run on-chain. That’s not a UX preference; it’s a structural choice that affects:

Settlement speed. On-chain settlement is automatic; no manual book intervention required.
Pricing transparency. Order books are visible; there’s no hidden margin layered into displayed odds.
Censorship resistance. A crypto-native exchange is harder to shut down than a centralized book — relevant in jurisdictions where licensing is restrictive.

For most U.S. bettors, this distinction won’t matter day-to-day. For sharp bettors evaluating where to put real money, it matters a lot. A crypto-native exchange may offer structurally tighter pricing because there’s no operator margin built in — just the market clearing on its own. The trade-off is liquidity: thin order books mean you can move the market with size, which cuts both ways.

Insight #3: For U.S. Bettors, Crypto Sportsbooks Solve a Specific Problem

Strip away the crypto-evangelism framing and ask the practical question: why does a U.S. bettor use a crypto sportsbook? The honest answer, in 2026, comes down to three reasons:

Access to international or offshore books that U.S. operators don’t compete with. Most regulated U.S. books offer similar pricing and limits because they’re competing for the same customer base. Offshore crypto books often price more aggressively, especially on niche markets and props.
Higher limits and no-restrict policies. Crypto-native books generally don’t run the same anti-sharp account-management software U.S. retail does. A bettor with consistent CLV won’t get limited at $50 the moment the book identifies them.
Withdrawal speed and reliability. Crypto rails clear in minutes versus 3–7 business days for ACH withdrawals at U.S. retail.

That’s the honest case. The dishonest case — that crypto sportsbooks have inherently better odds — usually doesn’t survive contact with the data. Pricing varies; some crypto books have wider lines than top regulated operators. The structural advantages are around limits, account longevity, and withdrawal flow, not bet-by-bet vig.

Where Bet105 Sits in This Picture

Bet105 operates in this offshore-crypto-friendly category — built around the bettor profile Eccles described: customers who want competitive pricing, real limits, fast crypto withdrawals, and a no-restrict policy on winning accounts. That’s the sportsbook category sharp bettors actually use, because it solves the limits and withdrawal problems that kill long-term U.S. retail play.

This isn’t a pitch for crypto over traditional banking — many bettors still prefer fiat for tax and tracking reasons. It’s a description of what the sportsbook market actually looks like once you accept that “U.S. regulated retail” and “international crypto-friendly” are different products serving different needs.

A Real Example: The Withdrawal Math That Most Bettors Underweight

Imagine a bettor who shifts $5,000 between books over the course of a season — withdrawing winnings, redepositing for the next slate, and so on through ~20 transactions.

At a U.S. retail sportsbook: ACH withdrawal averages 3–5 business days, with some books holding for review on amounts >$1,000. Total time-cost across 20 transactions: roughly 60–100 business days where money is sitting in transit. If the bettor’s annualized return is 15%, that’s ~$240 in foregone yield.

At a crypto-rail sportsbook (e.g., Bet105): withdrawal clears in minutes-to-hours via stablecoin, then off-ramps to fiat in another minute or two if needed. Total time-cost: hours per transaction, days per year. The yield drag is effectively zero.

This is a small example, but the underlying point generalizes: crypto rails compound advantages most bettors only notice in aggregate. Faster cash flow, fewer points of friction, fewer touchpoints with risk-scoring software.

The Takeaway

The “best crypto sportsbook” question is usually framed as a comparison between operators — pricing, bonuses, sport coverage. Those comparisons matter, but they’re downstream of a more fundamental question: what category of book serves your actual betting profile?

If you’re a recreational U.S. bettor placing two-team parlays on Sunday afternoons, regulated U.S. retail is fine. If you’re a serious bettor running real volume, tracking CLV, and getting limited at every book that figures you out — the answer the international crypto market keeps giving is: come over here, this is built for you.

That’s the structural shift Eccles flagged. Crypto sportsbooks aren’t competing with FanDuel for casual customers. They’re serving the customer FanDuel doesn’t want.

FAQ

What is a crypto sportsbook?
A crypto sportsbook is a sports betting operator that accepts cryptocurrency deposits and withdrawals — typically Bitcoin, Ethereum, USDC, or similar. Most operate offshore relative to the U.S. and serve international markets directly, since U.S. regulators have not broadly approved crypto as a deposit mechanism for licensed sportsbooks.

Are crypto sportsbooks legal in the U.S.?
The legal status varies by state and is genuinely ambiguous in many cases. Most crypto sportsbooks are based offshore and operate in a legal gray zone for U.S. customers — accessible without violating federal law in most circumstances, but not licensed by U.S. state gaming regulators. Bettors should research their state’s specific position before depositing.

Why do most major U.S. sportsbooks not accept crypto?
Because U.S. state gaming regulators haven’t broadly approved crypto as an accepted deposit method, and U.S. banking infrastructure treats crypto-to-fiat conversions as high-risk. As Nigel Eccles noted, even tier-1 operators like DraftKings can’t accept crypto deposits inside the U.S. regulatory perimeter. The challenge isn’t technical — it’s regulatory.

Are crypto sportsbooks better than regulated U.S. sportsbooks?
Different, not strictly better. Crypto sportsbooks generally offer faster withdrawals, higher limits, and looser account-management policies for sharp bettors. Regulated U.S. books offer state legal protection, FDIC-banked deposits, and stronger consumer protections. The right choice depends on whether you’re optimizing for safety/regulation or for execution and account longevity.
