Duelbits vs Underdog: One Blocks the US, One Doesn’t

Duelbits and Underdog end up compared for one reason: both surface under the same kind of gambling-adjacent search, and neither is what the query implies at first glance. Duelbits is a Curaçao-licensed crypto casino and sportsbook that has never accepted a US signup. Underdog is a Brooklyn-founded daily fantasy company that used to also run a sportsbook, closed it, and now sits reachable in most states under a completely different product. Put side by side, the gap between them says more about US online-gambling law than either brand does on its own.

Is Duelbits or Underdog Legal for a US Reader?

Underdog’s legal footing is genuinely state-by-state and product-by-product — Classic Pick’em runs under roughly 15 states’ DFS exemptions, Pick’em Champions is separately licensed starting with New Jersey and Delaware, and nine states block the brand outright. That is a real, navigable map. Duelbits has no map to navigate: it excludes the United States alongside dozens of other jurisdictions, including the UK, Australia, and most of western Europe, and no state license would change that — Duelbits simply does not open US accounts.

Is Duelbits Legit If It Won’t Take Americans? Is Underdog Legit If New York Fined It?

Both questions have real answers that don’t cancel each other out. Duelbits is legit by offshore standards: six years of continuous operation, a direct Curaçao license rather than a resold sublicense, and sponsorship spend — the Team Liquid title deal, the Birmingham City FC shirt — that only makes sense with real revenue behind it. Blocking the US isn’t a legitimacy problem; it’s a business decision plenty of Curaçao operators make. Underdog’s $17.5 million New York settlement is a real enforcement action, not a rumor, but it’s also the kind of thing an illegitimate operator doesn’t pay and keep operating everywhere else through. Getting caught and correcting course reads differently than getting caught and disappearing.

Is Either One Safe to Actually Use?

Underdog’s safety case is straightforward: a US company, a public settlement history you can look up, and payouts through PayPal, Venmo, and Trustly. Duelbits’ safety case only applies to players outside its block list — for anyone else, including Americans behind a VPN, the platform’s terms are being violated the moment an account opens, and identity verification at withdrawal is exactly where a blocked location tends to surface. That risk sits on top of the US player’s money, not just their account access.

Which One For Who

A US reader who wants pick’em-style fantasy contests, in a state where Classic Pick’em or Pick’em Champions is actually offered, has a real option in Underdog — check which product, since the two aren’t approved in the same states. A US reader who wants what Duelbits offers — a crypto-first casino, a full sportsbook, zero-wagering free spins — has no path to Duelbits itself and should look at an operator that actually accepts American accounts, like the Bovada review on this site. A non-US reader outside Duelbits’ block list is the one person this comparison doesn’t really apply to — Underdog is a US product with no presence outside the country at all.

Neither product is a way to make money. Duelbits runs on a house edge like any casino or sportsbook; Underdog entries are real-money risk even though the scoring is fantasy, not a wager against the house. Treat either as entertainment spending, never income, and confirm the specific product and state before assuming either one is open.
