According to Cas Abbé, Grayscale has transferred $90 million worth of Bitcoin to Coinbase, reinforcing its status as a net seller in the crypto market since 2021 (source: @cas_abbe on Twitter, May 26, 2025). Historically, Grayscale's negative premium triggered significant institutional bankruptcies during the last cycle. This ongoing selling trend could increase downward pressure on Bitcoin prices and signal persistent institutional caution, which traders should monitor closely for potential market volatility (source: @cas_abbe).
