(No point including some of the BTC sportsbooks that offer ridiculously low value odds - opportunity of finding arbs on better books is wasted)
So you will be using Fairlay, Cloudbet, Nitrogen and any UltraPlay book? No other ones with good value AFAIK.
I checked the email I got yesterday, and while I "subscribed" when it showed that I would get the first month free, the email said I would get only 30% off. Why is this?
Indeed, experienced arbers will agree that most arbs come from a small selection of books - they are no way near evenly distributed, and do not scale linearly.
Very true. The ones I mentioned (and CoinBet24, who limits you) are pretty much the ones that give the most arbs. Maybe jetwin sometimes, but I haven't personally used them.
