I can say that showing us any evidence is absolutely not needed, it's not necessary since the op doesn't owe anyone that, he has asked anyone to contact him or subscribe to his games by paying any form of fee, he simply shared a strategy he claims he has been using and it's been working for him, you either believe him and maybe try to copy the same strategy yourself, or disbelief him and ignore the strategy, asking him to share or post evidence is absurd.

And let me also say when it comes to sports betting, I believe it's very possible for a bettor to stay in profit for a very long time, that is, their overall profit is much more than their overall loses in the long run and even up to or more than 10 years, it all depends on how knowledgeable the bettor is in and or with sports, and also how lucky they are with betting in general.

You have been using this for over ten years now and you have had more profits than losses. It's hard to believe that such a betting system can work for such a long period of time. Placing multiple bets at the same time is very risky because there's a high chance of losing everything. You also claim to be a pro at this strategy. If this is really true then you must become really successful from gambling now. If you can show us some winnings for us to be convinced that you are as good as you are then this would be valid.

If everything was presented by OP at the moment that he had posted, then he wont be able to get some bashes or this thread wont become too long about replies in regarding for this thing to be a shit.
Anything that claims about sure win and making sure money specially on gambling or betting world, then 101% of those things are totally BS. Just like on what been said earlier by some posters that if this one really works then you wont be wasting up your time on trying out to share it into public and for this one it do shows that OP doesnt give out any clear tips or whatever the ways that he do wants to share up. We do know that there's no such thing about assurance when it comes to sports betting. Lets say that you are pro but it doesnt mean that have that holy grail method. Come to imagine on having that 1k capital and making 7k in a  month period on which its possible though but disclosing up the method? There's no such thing because choosing up which team who would win will always pertain about basic analysis and decision making on whom you do choose on.

Actually it could work, and since he had been talking about 10 year experience with sports betting then if you do find yourself already that a professional and profitable, then whats the point on trying it out to boast into public. In what sense that you are trying to prove out? You do expect people to tell and praise you on what you have achieved or simply that wanting to have some cliff-hanger and people do get curious on what the strategy is all about?

Multiplying the bet amount by 7 times isn't bad at all. I thought about applying this strategy to other games, like roulette, betting on black or red, even and odd, 1 to 18–19 to 36, for example. Splitting it into 3 larger bets, approximately 33%, on each, instead of choosing one number, which pays more, but is also the most difficult.

It may not be feasible, but OP's strategy gave me some ideas…

Yeah, you are absolutely right, 35 days to make a total of x7 profit with a starting capital of $1000 seems pretty conservative if you ask me, very conservative actually because any other gambler like my very self will no doubt aim for much more than that, I did try to turn that $1000 into $20,000 in less than 20 days or in 20 days max, but this also explains why many of us end up losing far more than we win and last last, end up losing the capital if care is not taken.

Reaccessing everything that op said about his strategy and what he has achieved from it gives me the impression that his level of patient and lack of greed played better roles in his success with this strategy than the strategy itself, this is aside being lucky though, for every thing always falls back to luck in the end.

A kind of mentality on which a certain lazy person could have, or lets say that someone is waiting up for some airdropped you say or literally some government aide. If we do speak realistically about on those wealthy people who do sit up on the top of the chain, they can actually provide such money and they do still have tons of money left into their banks. The question on here is that would these people are willing to make out such act? Never ever in our dreams and instead on stressing yourself on mandating the government and with those millionaires/billionaires to do such thing. Why you cant just that simply work hard your ass off and do mind your own business and dont dream that those who are wealthy would be airdropping 10-20k on your bank account. They do work hard and achieve success without the help of other people or simply they have grinded themselves and just giving out to people? There's no way that it could happen.

Money cant be easily be given and lets just accept the fact that we are thriving ourselves to achieve something for our own survival on day to day basis on which is the reason on why we are trying to find tons of sources of possible income stream for us to have that kind of sustain at the time that we are living at our own, how much more if you do have a family? You cant just that simply sitting down and wishing up for those wealthy people do give out some airdropped money into your bank account. hahaha

The only thing that i do wait is on the moment that - "You wanna know the rest of the strategy? DM me."

If im that someone who could be able to make $7k out of 1k for 35 days then i would just simply spoil myself and grind into our house attic and make myself rich. 
I wont be that minding that much about telling the public or posting in forums that i do have some strategy like this and like that.

All we do know that sports betting is all matters betting on a particular player/team whether it do wins or not. Odds will be based and just those calculations above
then its just the basic stuff. Strategies will differ but it wont be giving out guarantees.

OP, you turned $1k into $7k in just 35 days, seems impossible to me. Did you place a total of 8 bets with $1k? How many dollars did you put in each bet?

However, I personally think that not everyone will benefit from using the same strategy, because gambling involves luck. Also not everyone can afford to deposit so many dollars, in my case I can't afford to spend more than 30 dollars in 35 days, so I can't expect to win a huge amount of money in a short period of time. In fact, one cannot expect to win big with a small amount of money in sports betting.

Honestly speaking, this nonsense doesn't sound like it's coming for a winning player that's "doing over 10 years and is a pro in this ". First of all, bankroll management isn't a strategy. Also, this kind of bankroll management is kind of a guaranteed loss. 10% of the total money in 1 bet, yeah right. Lose 5 bets and half your money is gone quick.
Better think about another way to "earn" money because I don't believe you make any with this kind of stuff.
