Well I do bet, and I do have money. The principle is easy, prior to any oddline scoping on various sites to find the best odds for a particular fight, have word files or paper notes of specific things about each fighter. Take your time analyzing; I have spent hours analyzing most every fighter in each weight class and from various orgs as I want to cash in on upcomers when they do hit the UFC. Then take the information you have, create YOUR own odds to what the likeliness is of particular fights. Now go scope out the multiple websites that you ought to have accounts in and find the best value. If you believe a fight is a 80% chance of going in the favored fighters direction and oddlines have it as 1.4, take that bet all day long.
For those talking about slipping and breaking ankles or randomly getting injured; how many can you name of the fights you've watched?
Conor in this fight imo is going to absolutely punish siver who ALWAYS throws the left hook for anyone who advances on him. In his fight vs Charles Rosa his timings were so predictable and movement was completely rigid. The only reason I think he even beat Rosa is because Rosa took that fight on 12 or 14 days notice? Watch for Conor to feint and crush siver when he misses on the left hook. Hell Conor has so many options in that fight its not even funny.
Stay away from prop bets in most cases. Prop bets are typically a sink hole, not that you can't hit them, but on average you are much better off betting the more basic bets. Bet to watch the account grow, get your high off watching the money increase, don't bet to get the excitement levels higher. Once you get addicted to the highs and lows of gambling, you're on your way to becoming an addict. Winning $5.00 is better than almost winning $275.00 on a $10.00 parlay that you tell yourself "well it's just ten bucks."
