Live bets seems like a waste to me as you do not really have the time to tell if the odds you are being offered are any good, I see most of those bets to be there for the compulsive gambler that wants to bet on anything and everything, ....
Live betting is good for people who are watching the game, but haven't tried putting live bet with a very high odds, normally I do live betting and put a bet on game only and that is on either the point spread, totals, or betting SU.
