The over lines were never at evens when you checked. When you saw 1.87, the Under was at 1.97. This is a 4.2% margin which is only slightly higher than Pinnacle's 3.6% and understandable for a game that sportsbooks can't very accurately price. This is consistent with other sharp books. All books shifted the line upward (likely due to sharps hammering the over), and Nitrogen's volume is almost certainly not high enough to cause line movement. The Over 311 line also started on Jan 15 as 1.93 evens on Pinnacle, so 1.92 evens on Nitrogen. Not their fault you didn't bet early enough. I highly doubt any book offered 1.93 or higher when Pinnacle was down to 1.87 as only slow moving sportsbooks would still treat the line as evens and they generally run 1.91 or lower evens.
If it was 1.87 evens, then you can complain. But, that was never the case when you saw the line, and if Over 311 was a 50/50 bet, then you'd get 1.92 odds from Nitrogen. This is like complaining that they don't give you 1.92 odds for a full Manchester City squad to beat Huddersfield in the EPL (top team vs bottom team), which is very reasonable as the chance is not 50%.
Pinnacle allowed you to buy a point or sell a point for higher odds, just like they do with all NBA games - but Nitrogen did not allow it this time.
For instance, when the line went up to 313 you could have easily bet OVER 315.5 for over 2.XX odds in Pinnacle but Nitrogen (1) did not offer these options (2) had the stakes limited to half a Bitcoin.
Also unlike Pinnacle, Nitrogen doesn't allow you to bet 0.5 BTC and then place another 0.5 BTC ... once you hit the limit you can't place any other bet until the limit is raised - Pinnacle does allow you to place several bets on these big events.
So the comparison you made to Pinnacle is not similar neither for these reasons.
Nitrogen lines are Pinnacle lines with a bit more juice, so Pinnacle lines are very important in determining what Nitrogen offers. (they copy Pinnacle)
You checked the lines at a very bad time. When Over 311 was @ 1.87 on Nitrogen, Pinnacle did not offer any alternatives. They opened Over 312 @ 1.93 about 12 hours after the 311 line shifted to @ 1.87, and allowed you to buy/sell points about 24 hours after the Over 312 line opened. It isn't Nitrogen's fault that Pinnacle had no alternatives when you checked the line. My historical data verifies that buying points was unavailable for about 36 hours after Over 311 shifted to 1.87.
Do you have data to backup that buying/selling points was available during this time period, or are you making unsubstantiated claims? My data could be incorrect, but I highly doubt it.
For limits, my guess is that they weren't comfortable taking very large bets on a market without very good price making. They have every right to do so, and their limits are good for normal NBA matches. Also, Pinnacle allows more bets because they can shift the odds, and Nitrogen technically can but they don't, as they aren't market makers.
@Get-Paid.com, if you believe this:
Does that mean that 1.64 increases the "likelihood of that event to occur"? No.
Sometimes games end near the line and "buying a point" might be worth it, but you can never know when it would happen and by placing 1.60 bets you are killing your bankroll.
Why aren't you selling points on every event? If a 1.64 odd means that the line is still 50% probability, taking the other side @ 2.36 gives you an 18% +EV bet. Think of all the profit you could be making!
Oh wait - it doesn't work that way.
