New phone and new stuff

Well the 23 of agoust was my 18 birthday and my parents gave me a new phone, i use it only for playing Animal Crossing Pocket Camp, i should use it for something else i think but until my old phone dies i will not use it.

Anyway, of all my parients i gained like 137.300 Argentine Pesos (Wich is like 130 dolars),  i should use the money for something o i keep it there until i remember i have it?
