Why can't I sell on Coinbase?

One cannot sell on Coinbase if there are certain restrictions on their account, which could be due to several reasons such as not meeting the eligibility requirements based on geographic location or not complying with the verification processes. Additionally, regulatory constraints in some regions may prevent users from selling cryptocurrencies on the platform. Technical issues with Coinbase itself or the individual's bank or financial institution that is linked to their Coinbase account could also impede the ability to carry out sales. It's also important to ensure that one has the necessary funds or cryptocurrencies in their Coinbase wallet and that there are no security holds or account reviews underway that would temporarily restrict trading activities. If these factors are not the issue, reviewing Coinbase's terms of service and any recent communications from Coinbase may shed light on why selling is currently unavailable.
