Even without proof, I still doubt he can turn $100 into $10k. Every time he loses, he has to start from scratch, so it’s likely he’ll just get tired of posting because he can’t reach the goal. I wonder how his last bet went - any updates? Sorry to ask, I’m not too into football or soccer betting.
He update with new reply but still he doesn't give screenshot of his bet ID. We can only check the match or visiting Stake.com to see if he wins or lose. Many of us doubt with his bet so he really need to show the proof to us.
UPDATE: There seems to be some confusion in the thread regarding Bet #3, I originally deleted it because I cashed out BEFORE the second half began, but I fell asleep before I could update the thread, I'm sorry!

It wouldn't have made a difference because Bet #4 lost.

I have updated my post with links to my betslips where you can see every bet I placed. I will start again with a fresh $100 balance and hopefully I can succeed this time, and I will try to avoid live bets from now on!

Bet #1: MLS: Inter Miami CF - Atlanta United FC
Over 1.5 Goals 1st Half @ 1.92 odds (via Stake)
$100 to return $192
Where is the link? You say you want to add the link.
I wonder what is your balance position since beginning? How much winning you already got?
I updated my post with links, so if you click on "Over 1.5 Goals 1st Half @ 1.92 odds, it will open the betslip. I also responded to someone with the link above. I am currently at $192, I am attempting the challenge for the second time.
