I don't trust and never used any insider info.
Most so called ‘insider info’ or claimed ‘hackers’ are just members of the betting site promotion team. They offer betting tips or insider info just to get people to use the website and gain traction on the website. People obviously lose money at the end.
John Mcafee sometime said ‘If you believe someone somewhere for no good reason is willing to give free money, then you Will be scammed’ (something like that, but you get the picture).
