Money laundering is Spain is record high. Unaccounted transfers using SEPA in EEA regions lead to this measure. You can literally send money from one EEA country to the other in 5 mins.
So, in Spain there is record money laundering using electronic money transfers and to combat that, the Spanish government decides to further limit physical cash and force everyone switch to electronic money?
I was going to respond to him too but if you look at his profile and his recent post history you will see that he is not to be taken seriously.
On the downside, the good thing about Spain compared to other countries, for example the UK, is that all businesses are obliged to accept cash the €1,000 limit. In the UK, businesses can decide not to accept cash and that's it. In this sense, and despite the restrictions, I would say that today cash is still used much more in Spain than in the UK, despite all the obstacles they put in place.
