Alright, I saw this news and I have to say it's quite heavy for Jack Dorsey. Hindenburg Research just released a report on Block Inc., accusing the company of inflating user metrics and ignoring widespread fraud. On Thursday, the stock plummeted 22% during the session, closing down 15%.

But what hits the hardest is the impact on Jack Dorsey's personal wealth. His net worth dropped by $526 million in just one day — the worst decline since the previous May. Now, his fortune is around $4.4 billion, an 11% decrease according to the Bloomberg index. The interesting part is that most of his wealth is directly tied to Block: Bloomberg estimates his stake in the company is worth about $3 billion, while his position in Twitter ( now owned by Elon Musk ) is valued at only $388 million.

Of course, Block denies everything and says it is considering legal action against the short seller. This isn't the first time Hindenburg has hit with such reports — remember Gautam Adani earlier this year? Nikola Corp. was also targeted a few years ago, with legal consequences for the founder.

What I notice is that Jack Dorsey has a rather high concentration of risk in a single company. When fraud allegations emerge, even if contested, the market reacts violently. Situations like this remind us how important it is to diversify and not put everything into a single position, especially when the company's reputation is at stake. Anyway, if you follow these movements, you can also track them on Gate, where you can monitor the stock's performance and related assets.
