These types of mistakes happen when the person is intoxicated by seeing examples on social networks , seeing how some win and how tremendous sums of money are made in a quick moment and without effort , what happens is that the reality is different, real life outside of YouTube and any social network where that is seen is different the person who does that and loses everything knows that they were wrong , that they should not be greedy and that the best option is to see the game as a Business where if you get Small profits you Should settle for it and then play in another game session, I see gambling like that.
You are very well correct, social media and groups have become a breeding ground for all those sure bets and code sellers, where they promote their fake winnings and if a newbie is not careful they fall into paying some fees just to get some random codes to bet on, and most of them end up with bitter stories at the end, so what is most important is to avoid all those social media claims and focus on personal experience.
Just settle things the way it should, use spare and take that risk where you can handle the pressures, the amount of your stake should be the one that you can afford to let go, so no matter what happen you can move along and settle things out, no need to outreach to those so-called experts where most of the time just sucking followers money, directly or indirectly they can manage to earn thru referrals or a sponsor cut or thru subscriptions.
