Mouthwatering lineup if true
🚨𝗠𝗔𝗝𝗢𝗥 𝗕𝗥𝗘𝗔𝗞𝗜𝗡𝗚: David Beckham is reportedly exploring a sensational move to bring Cristiano Ronaldo to Inter Miami in January, with the intention of pairing him alongside Lionel Messi. Beckham’s biggest motivation is reportedly to fulfil Ronaldo’s long-standing dream of sharing the same pitch with Messi before both legends retire.🐐

Football bloody hell
🚨 Sir Alex Ferguson’s emotional letter to Cristiano Ronaldo following his retirement from international football: 🎙️ “Cristiano, I don’t know if you will ever fully understand what you have meant to football, to Manchester United, to Portugal, and most importantly, to me. When you first walked into my office as a young boy from Sporting Lisbon, I saw something special. I saw hunger, confidence, courage and a boy who believed he could become the best in the world. But even I couldn’t have imagined the heights you would eventually reach. I remember the young boy who wanted to take on every defender, who stayed behind after training and who was never satisfied with being good enough. Sometimes I had to remind you that football was a team game, but I never wanted to take away that fire inside you. Today, as you close another chapter of your international career, I want you to know that you have given your country something that cannot be measured in goals or trophies. You gave Portugal belief. You carried the hopes of millions, you cried for your country, you fought for your country, and you eventually gave them a European Championship. You made an entire generation believe that nothing was impossible. I have watched you grow from that talented young boy into a man who has challenged the limits of this beautiful game. And I must tell you something: I am proud of you. People will argue about who was the greatest. They will compare your records, trophies and achievements. But when I look at you, I don’t just see a footballer. I see a young boy who refused to surrender his dreams. You may be saying goodbye to international football, but you will never say goodbye to the memories you have given us. And if I could speak to that 18-year-old boy I brought to Manchester all those years ago, I would tell him one thing: ‘You have no idea how many lives you are about to touch.’ But there is one thing I must say. I don’t believe this is how your international journey should have ended. A player who has given so much to his country deserves a much greater honour and farewell. You deserved to walk away with an entire nation celebrating your extraordinary contribution to Portuguese football. Portugal owes you more than a goodbye, Cristiano. You deserve a farewell worthy of a king. Thank you, Cristiano. It was an honour to be your manager, but it was an even greater privilege to watch you become the man you are today. You will always be my boy, Cristiano.”

You can just do things - gone wrong!
Our investigators are observing never-seen-before laundering patterns with the stolen funds from the Binance exploit. Thousands of transactions in a short period suggest that the attackers are using automation to obscure the trail of funds. Rather than simply moving funds onward, they repeatedly circulate them among addresses, often sending funds back to addresses involved earlier in the sequence.

Catch me if you can part duex? I think they should cast Leo again.
The Binance hacker might have just executed one of the most brilliant moves in crypto. First, Tether froze $1.5 billion worth of USDT. Then Circle followed by freezing another $800 million in USDC. At that point, it seemed like the hacker’s funds were completely trapped. But apparently, he had already thought several steps ahead. Rather than keeping the stolen USDT in a wallet, he allegedly deposited it into Aave and used it as collateral to borrow ETH. Then he walked away. And this is where things get really interesting. Tether can freeze the USDT sitting in that wallet. But it can’t freeze the ETH that was already borrowed. So now, Aave is left with frozen collateral, while the hacker is holding liquid ETH. And unless the protocol finds a way to recover those funds, he might not even have to repay the loan. Two companies froze billions of dollars in seconds. Yet someone who understood how DeFi works may have found a way to bypass both restrictions. Pretty wild when you think about it.

BREAKING: Intel stock, $INTC, extends losses to -27% on the day, now on track for its biggest daily loss since 1974. This puts the stock down -53% from its June 30th record high. That’s -$400 billion of lost market cap.
