Opinion on each book's live betting:
Anonibet has the most options live. Alt lines, totals, etc. Normally it's around 17 markets each game NFL, more for soccer.
Betcoinsports - I like the interface and it's very easy to use. You can change the view to either American or European.
Casinobitcoin - Not as many options and there are problems getting bets in. They have a 20 second countdown until lines change. There is also a delay after you place your bet. Coupled together many times bets are rejected because of a line change. Casinobitcoin is still a good book.
Cloudbet- They are a good option but there are complaints/snags with the live betting. They are another good book.
BetVIP- Somewhat similar to Anonibet.
All 5 books above are good books. They have strengths in different categories.
