This article is about the possibility to add your own currencies. You can add as many currencies as you like.

Again, I wanted to give the users of my app full freedom to add their own currency. As a standard, it is best to use a three-letter abbreviation, e.g. EUR for Euro in my case. Or e.g. for US dollars then USD.
