Ah lol, I knew it - most of services like this are mostly run by troubled person.
They do this not because they are good and pro on sports but because they are also broke and need money to gamble.
If they always win, why bother to selling this service.
They don't need to gamble if they are making money from this offer. It's a risk free for them as when you subscribed you'll just pay for the fee and you get the information you want, question is, how reliable the information is. Nowadays, with the sportsbookes or odds makers uses more sophisticated tools to prevent this thing or any lapses that can be abuse by certain people, so it's quite doubltful if OP had really succeeded on this or it's just a false promise.
For sure all of the information they shared is questionable since if they can hit those accurate information that can help a gambler to win then provably that they will not share their methods used. Only those shady person claiming something outrageous and those people read this should start to doubt on the service they are trying to offer. More better for people to stop trying to look after those what they called expert prediction or anything they call that since usually the random person offering this are trying to take advantage those greedy bettors who want to win and they are perfect target to those scammers to scam. People should stop listening on false promises but rather they should do a research.
I quite understand your plight, but it is not particularly true. The fact that an expert understands a thing and earns from it doesn't mean the expert can't still broadcast it. Some may keep it to themselves and earn alone through it, while others may want to commercialise what they know even as they make more money separately from it. This means two means of earning for them, and what many are not taking seriously which is the commercial ones may be earning more for the gambler in some cases. Your consideration has been happening in the financial market prediction for long, so I quite understand this, but people are different.
What I will advise anyone to do is to first go for the free trial the guy offers, after all, you are not paying a dime for it. And if he changed his claims and asked for the money, you should just excuse yourself from his channel. We cannot always be commenting or faulting what we have never tested, we are not perfect, and what if he is right? For the casino bettings, I know 100% that it will fail. But for sports betting, I am still 50% in my belief that there are some spectacular predictors, but how do you know if you never give them the benefit of the doubt to at least try them?
