As banks buy up bitcoins, who else are the 'Bitcoin whales'?

Bitcoin’s price is nearing its all-time high, largely due to US finance giants like Grayscale, BlackRock, and Fidelity investing billions into the volatile digital asset.

The shift in wealth raises questions about the future of the digital currency that was originally created as a peer-to-peer internet money. The figures below are estimates gathered from direct research and published information.
