Coinbase Newsroom report: Coinbase founder Brian Armstrong responded on X to user concerns about his continued sale of COIN shares, stating: "I did sell, but after 13 years of starting up, wouldn't it be too crazy if I still had 99.999% of my net assets in a single stock? So this is an inevitable choice. However, the vast majority of my current net assets are still in COIN, and I'm very optimistic about the future. At the same time, I've also used some of the proceeds to help establish more companies."
