#MarketSentimentToday Just when Bitcoin starts to feel the love again, a dark shadow approaches. The crypto market shows signs of life this week, signaling a potential year-end rally. But hold on, because Mike Brock, a former executive at Jack Dorsey's Block (you know, the company behind Cash App), just dropped a bomb.

Brock basically said Bitcoin is finished. Like, "Bitcoin will fail. Because it is a lie" finished. Ouch. Of course, this caused chaos on social media. But here's the thing: Brock is not some random internet troll. He’s not just a hater. He used to be an insider.

Think about it. He was a software engineer at Block, helping to build Square Cash, which eventually became the Cash App we all know. He has seen how the system works, the good, the bad, and the ugly. Cash App just launched a feature that allows millions of its users to pay with Bitcoin even without having it! So, he knows what he's talking about.

So, what does this mean for your crypto portfolio? Well, it's a reminder that even with the recent rise, Bitcoin is still a wild beast that is easily volatile. When someone who used to be in the inner circle starts shouting from the rooftops that everything is fake, it might be wise to pay attention. Maybe it's time to reassess your strategy, or at least prepare for some potential turbulence. Brock's warning is a wake-up call, and it definitely has the crypto world buzzing. #BTCbuzzkill
