Grayscale Investments has purchased almost half a billion dollars in Bitcoin since the May block reward halving, and this week bought BTC around three times faster than miners could produce blocks.
According to a June 25 tweet from crypto analyst Kevin Rooke, the investment firm bought 19,879 Bitcoin (BTC) — $184 million worth — in the last week for its Bitcoin Trust, bringing its total number of coins to roughly 400,000.
