Reliance on sites that offer free predictions or even paid predictions may not be the way to be a gambler because without them you feel like you will not be able to gamble and analyse games to get results on your own. I do not criticize anyone currently using this sorts of website, but my advice is that you should try not to get two dependent on it.
Almost everyone literally uses same strategy of checking at previous meetings of the two teams that wants to play a match, also check other statistics like the outcome of previous current matches, the home and away outcome of the previous matches of both teams and others so it is normal to analyze the option you choose for an event based on this things but anyone who relies on betting sites for predictions is not a gambler since you can't make predictions of your own without depending on predictions sites, most of this sites predicts just like normal gamblers do predict so there is nothing special about their predictions even if their predictions works most of the time but a gambler don't need to depends so much on gambling sites before the can place bets.
As long it would really be that giving or making at least some viable application into your analysis on which you do make out some combination then it wouldnt really be that a bad idea after all.
Just make it sure that in the end on which you are really that basing up into your own rather than on other sources on which it wont really be giving out that kind of regret on the time or moment
that you do find yourself on a losing situation.
