300,000,000 USDC was transferred from the USDC Treasury address to a Coinbase address, according to Whale Alert. This is a transfer worth 300 million dollars. The reason for this large transfer is not yet known, but it could be related to a large trade or investment. It's worth noting that USDC is a stablecoin, which means that its value is pegged to the US dollar. This makes it a popular choice for investors who want to store their funds in a stable and predictable asset.
