Welcome to bitcointalk forum!
I see that during registration procedure on your website we are getting some BITCOINTALK bonus, so what is that exactly?
Second thing I saw is that Bitcoin and all other coin withdrawals are free, does that mean we don't have to charge transaction fees like in Sportsbet.io?
1. BITCOINTALK bonus code gives you just some small amount of extra cash to start with (+5%). In February we will also offer +100% Deposit Bonus but just like all of deposit bonuses - it will come with a higher turnover requirement. Users will have a freedom of choice - small bonus/small turnover or high bonus/high turnover. On top of that there are Daily Giveaways, Weekly Races and Monthly cashback gift cards among other (event based) promotions. We're also building some cool mix of rakeback and cashback system so stay tuned for more details!

2. Indeed, we cover all transaction fees on withdrawals.
