Due to a lack of time (travels) I would like to recommend you Mike Maloney's film Mike lays down basics about currency and money and the difference between those two. You will find out how oversupply of currency lowers purchasing power of your savings. You will understand the reasons why every single currency with no backing in material good failed miserably. 

Please do not stop educating yourself after watching this video - Mike with his precious metal business is giving his subjective view but for someone starting his/her adventure with finance it is worth watching this film.
