Which book has best odds? Any suggestions?
They all break at different points. Here are some good books with decent lines for baseball:
Betcoinsports -106
Cloudbet -106
Casinobitcoin -106
Nitrogen -107
Jetwin -107
Anonibet -108 at best but has a good sized variance.
Some books rated lower have -110 and above.
You should look at all books for your own preference. Some books with higher holds are opinionated or move on action negating the hold depending upon the side. Even those books moving on air may be slow to move.
Players or books can add to it or correct me.
