Also the American jargon and style everywhere is quite off-putting and confusing for what I assume will be the majority of your audience.
Thanks for your feedback. This is simply a marketing and fundraising site, and not the actual site, so it wasn't our top priority and we obviously had some room for improvement. We've added a FAQs page that gives a lot of detail about the actual bet exchange, including the commission structure, so hopefully there is enough information there to answer the questions most people would have. https://ibetbtc.com/faq
As far as the American jargon goes, it's funny because only one of us is actually American, but you're totally right. We've toned it down throughout most of the site and we will continue to make further edits in the next day or two. One thing we're hoping to do by raising funds is to hire somebody much better at writing content than any of us are.
Thanks again for checking out the site. If you have time, it would be great if you could have another look and let us know your opinion of the recent edits.
