Castle Busters

What is Castle Busters?

As of today, submissions for the 2026 iGB’s Most Influential Women list are open! We are once again looking for nominations that highlight all facets of the sector, and the women who are championing change and acting as leading forces within their company, or the sector more broadly.

Please provide as much detail and insight as possible on the person/s you are nominating. The more information and background we receive, the clearer the picture of their career and achievements can be.

While it’s tempting to use AI to help you write a submit, we please ask that you avoid doing so, as once again, the more personal an entry is, the better we can judge it across our key criteria.

How to play Castle Busters

Looking back on my 11+ years with CalvinAyre.com, I’ve made life-long friendships, attended countless industry events, interviewed hundreds of leaders, made thousands of contacts, built deep relationships with organizers, even had the honor of delivering a DAF award or two back in the day (who remembers???!!) but best of all, had the pleasure of working with some of the most incredible colleagues along the way, many of which who I classify now as dear friends.

When I joined CalvinAyre.com in August of 2009, there was an enormous gap in the industry for an honest, transparent news site with regular, fresh video content. Over time, we grew from a tiny team of a handful of people to dozens, providing the industry with the juiciest breaking news and cutting-edge video coverage. 

Today we pass on the torch to our event organizing and media production friends who have more recently developed outstanding news coverage and video teams dedicated to the gaming space, hopefully who I’ll be seeing at CoinGeek Conferences in the future.

“People will lose money faster on exchanges for lots of reasons,” Marantelli says. “It inherently increases spend, volatility, lots of things. And you’re playing against a sharper audience than you’re playing against at the DraftKings sportsbook.”

He compares the effect with sportsbook cash-out features, which gave customers more apparent control over their bets but may also have encouraged greater spending. The crucial difference is that an exchange customer can be facing a specialist whose entire business is identifying inaccurately priced contracts.

Kendrick sees a warning in the history of betting exchanges. In their early growth phase, there was sufficient retail liquidity for numerous market makers to profit. As that retail pool weakened, the sharper firms increasingly found themselves trading against one another.
