What are the potential risks or disadvantages associated with relying heavily on 'blogspot pmu tierce' predictions?

The main risks include potential for inaccurate predictions (which can lead to financial losses), lack of transparency in prediction methods, outdated information if blogs aren't regularly maintained, and the promotion of unrealistic expectations. There's also the risk of falling prey to fraudulent blogs that promise impossible returns or try to sell ineffective 'surefire' systems. Over-reliance can also diminish a bettor's own critical thinking and handicapping skills.
