I used to have a friend who constantly followed football (soccer). He just lived by this soccer. He could name members of almost all the Champions League teams from memory, and he knew all the drafts and sales of players. He knew everything that could be learned from public sources.
Accordingly, he won quite often in bets on soccer. He was even offered a job with a good salary in the team of one of the major bookmakers in our country. But he made a lot more money on betting.
But he never told anyone who to bet on and who not to bet on. I think that such professionals will never disclose accurate information on free sites.
That kind of person can really have good future in sportsbetting. Those who live and breathe the sport he is passionate about. And yes, it is true, most of these professionals really don't just give tips online. So if you want to be a successful bettor in sports, you should really be familiar with the sports you are betting with. The more you know about the sports, the higher is your chance in winning.
Such people can only have one problem. If they love one team, they may make biased bets on its games because of their attachment to it.
This professional attitude will definitely be enjoyed on its own and will not be published on free or paid websites, well if your friend has won big bets for what to work at one of the bookies if the income is still small from the bet then a professional will be better off silent and keep observing all about football and also how to run with these bets so I'm sure your friends are rare because it's hard to find someone like that.
If you know how to make successful sports bets yourself and earn good money on it, then you will never teach others how to do it, and even more so you will not tell them who to bet on.
