The announcement has caused concern among groups such as Denaria, which has been denouncing for years the restrictions imposed on the use of cash in Spain. Its president, Javier Rup\u00e9rez<\/strong>, has warned that the ECB's project is surrounded by uncertainty<\/strong> and questioned the speed with which it is to be implemented. \u2018We have nothing against the digital euro, but the dates have changed drastically and we still don't know if it will be treated in the same way as cash,\u2019 he said, according to Libremercado.<\/p>\n The concern of these organisations is largely due to the limitations that already exist in Spain on the use of cash. According to Denaria, the reduction of the limit for cash payments to 1,000 euros<\/strong> imposed by the government of Pedro S\u00e1nchez<\/strong> is one of the most restrictive measures in Europe. Under the pretext of combating the black economy and tax fraud, such regulations have complicated access to cash, something that, according to advocates of its use, could intensify with the arrival of a digital currency backed by the ECB.<\/p>\n
