I remember that we had a coin in game that would give you a random amount of zeny.
Could we alter that coin into a new coin and put in a npc so that we could turn 1billion zeny into one coin.
I know some have a huge problem with maxing out zeny and some items cost more than the max a character could trade thus producing a scenario where you have to trust the person not to run off with your item or zeny while trading.
So my thought is you go to the npc in Eden.
Give him 1billion zeny and receive the coin.
The coin would be tradable, storagable, (does not need to be vendable)
Then just double clicking it would give you one billion zeny if you have room for it.
Then you could trade easily with other people and also your merchant could have way over the max zeny amount. This would cut down on trouble tickets in the long run from item trades. Also it would calm down a lot of people who wish we could carry more zeny.
