Bro, I think is better make a special NPC to save your money, for example in a specific town will stay the NPC and if you talk with he/she he can save your money and return your money to your taste. In the differents regions: 1 in Kanto, 1 in Hoenn, 1 in Unova.
What do you think about this @Kyu?
Bro pokemmo sometimes is boring but you can do 2 things:
The 1st erase the game
The 2nd is see the positive to the game for example: you can meet really good people and make friends, you can too prepare strategies for unova PokeMMo has a lot of things to do just need to be discovered :)
