Here's a quote from the mail I got from Coinbase
Effective January 9, 2024, Coinbase will no longer support Bitcoin SV (BSV).
Users are able to withdraw BSV funds until support for this asset is deprecated on January 9, 2024 at or around 12pm ET. If you fail to withdraw your BSV funds, Coinbase will liquidate any BSV remaining in your Coinbase account. Upon liquidation, your BSV will be converted to the then-equivalent market value of another supported digital asset and credited back to your account, minus any transaction costs. Please note, after accounting for transaction costs, and subject to market fluctuations, you may not receive any compensation when the remaining BSV in your account is liquidated.
If you do not withdraw your BSV by January 9, 2024, you may incur tax liability or have other unanticipated tax consequences as a result of the liquidation or conversion and you are solely responsible for any taxes associated with transactions on Coinbase.
If you do not want your BSV funds liquidated, you must withdraw your funds by January 9, 2024.
Trading is not enabled for BSV and you cannot deposit BSV funds into your Coinbase account. Attempting to send BSV to your Coinbase account may result in a loss of funds.
