Buying tips from tipsters is an unwanted expense because they do the prediction similar to the way we do with collective data.
It really depends on the tipster. If that “trusted tipster” the OP mentioned consistently gives winning tips, then maybe it’s worth a shot.
In my opinion, someone who buys sports tips from a tipster shows that he does not really enjoy the game and even has the motivation to make gambling as one of the sources of income. There will be a sense of satisfaction when your bet is right but in my opinion if the victory does not come from yourself can you feel proud and happy with it? Most people who use the services of tipsters are usually addicted gamblers and hope to increase their chances of winning bets so they dare to bet a larger amount. I do not know how other people see tipsters but from what I heard from my friend most people buy sports services from tipsters because they want victory and money not because they enjoy sports matches.
