According to data from Arkham Intelligence, Glassnode, and Coinglass, more than 18,000 bitcoins were withdrawn from Coinbase during today's Asian session. The massive outflow of nearly $1 billion severely impacted Coinbase's exchange balance. These funds were sent to several different addresses, with new wallet balances ranging from $45 million to $171 million, and all UTXOs from the initial transaction have been spent. Coinbase currently holds about 390,000 bitcoins, worth about $20.5 billion. This balance is less than 2% of the total supply of bitcoins on the exchange, the lowest percentage since 2015.
