You need to have that knowledge unless you are fully good in taking that big risk, just by relying with the share picks from that paid subscriptions and wait for whatever the result will be, and like what you said, there's no guarantee even how high you are paying for that subscriptions, gambling is a always accompanied by risk and luck it's up to your judgement what to take regarding to paid subscription from that so called experts who are sharing their picks.
Having knowledge in sport betting is a must whether they use prediction site or use their own analysis. But many people doesn't want to learn more about analysis so they just rely on the prediction site to pick their choice to place a bet. They must know that the prediction site can not always gives an accurate prediction so we don't have to rely on them. It is all about how you willing to use your money to pay the subscription services because if you think that the subscription fees is too high for you, you will not subscribe to their services instead will trying to learn more about the analysis.
Yes, there will be no guarantee to always have an accurate prediction on every match so we must understand that if we can not wins any money from the prediction, we are only waste our money to pay the subscription. But some people are willing to use the prediction site so we can not force them to leave the site.
I agree! The additional tools are only for a good analyst, who already knows what he is doing (mostly), there will never be a 100% on any bet, however, it's always viable and possible to work a little bit harder to get a better understanding of the odds that are against you or on your side.
