Could you please clarify for me, is it possible to utilize the services of Coinbase in Spain? I'm interested in cryptocurrency trading and I've heard Coinbase is a popular platform. However, I'm not entirely sure if it's available in my country. Could you please provide some insight into this matter? Would it be legal and safe to use Coinbase in Spain? Also, are there any specific requirements or restrictions that I should be aware of? Thank you for your help in answering these questions.
