Here is what it says with regard to the limit of holdings:
"Digital euro holdings of individuals would not be remunerated and would be subject to holding limits, as provided for in the Commission’s legislative proposal.[18] These holding limits are intended not to prevent the digital euro from being a store of value altogether but rather to moderate its use in this capacity, and thus preserve the role of banks in ensuring the efficient provision of credit to the real economy.[19] In any case, users would have the option to link their digital euro wallet with a commercial bank account, allowing them to make payments through their digital euro wallet without needing to pre-load it with funds. This setup would enable large payments to be made with digital euro, irrespective of the digital wallet’s current balance.[20] In addition, this functionality would permit the receipt of payments exceeding the set holding limit."
