As far as I can see no one has complained in our forum
Exchanges board, but the problem you have is nothing new, it has been happening for years.
In short, Coinbase uses an automated system that checks user accounts and blocks them if it finds anything suspicious. They state that the two main reasons for this restriction of user accounts are chargeback and the lack of some information that would confirm your identity. Read their official explanation and send an e-mail to their customer service accordingly.
Sometimes buys and deposits can be disabled if your account is not yet recognized as a trusted payment source. Coinbase uses an automated system to help us protect the community and our site from fraud.
There are two common reasons for this type of hold:
If we have received a chargeback when attempting to process one of your trades, it may be preventing us from completing further orders. If you are aware of any chargebacks or reversals that have occurred on a recent trade, please include this information when contacting us.
In other cases, we may just need some additional information to confirm your ownership of the payment methods added to your account. If you have not done so already, please make sure there is an ID document uploaded at
