My advice to choose a good bookmaker for the online sporting bet is:
Choose a bookmaker, who have the “cash out” option.
Its the very same like the “Stop Loss” in the Forex market.
You can pull out the 70% of your betting money any time during the match with the “cash out” function.
That mean you don’t loose all of your betting money if something wrong happens.
I will send you the “cash out” signal too, if you subscribe for my weekly service (Just push the “Donate” button, $50/week.)
