Grayscale has transferred a substantial amount of cryptocurrency, valued at approximately $358 million, to Coinbase Prime. The transfer, which took place on October 14, involved 1,856 Bitcoin (BTC), 29,718 Ethereum (ETH), and 10,516 Solana (SOL). This move comes amid short-term market declines for these assets. On-chain data from Lookonchain and price snapshots from CoinMarketCap indicate that the transfers have coincided with declines in the prices of BTC, ETH, and SOL, which are often seen as potential sell pressure. However, Grayscale has not confirmed any sales following these transfers.
