I hear you but you have to understand what the other side of the fence is like. For a pro like me it can be hard to get on. Most bookies shut you down as soon as you have a few good wins and they realise your a threat. Bet limits are a problem too and there isnt always liquidity in the most exotic markets on bet exchanges like betfair. So I like to get on as much as I can and then if I can get a few more dollars sharing or selling tips it doesnt hurt me. It actually helps because the market will move in my favour which gives me the ability to trade or hedge if things turn. Most amateurs seem to think the betting markets are a bottomless pit of money for pros but they arent.
