1st suggestion: Exchange BS for items? Maybe something rare like health/rebirth pack, Jura trans, Elite sets? Or even membership, for those who have 1mil bs and above gets permanant member? But for those more than 1mil bs and above gets to have extra perm jura, dark meto and stuff. I know this will affect what people will buy on forum but maybe u could make new items or exchange their BS for Gigas and sell things that used to be sold on forum to be paid with USD, Gigas and Coins?
Next suggestion: Make coins not gainable from sector and change BS for coins. This will make coin very valuable and people might trade their BS for coins on forum.
3rd suggestion: Add new items to shop? Like rebirth pack, Guild name-changer or direct combination coupon(make an armour +7 immediately).
4th suggestion: I consider this one special (no insults please ._.) Like let the players have custom armour for bs. Make it look all the same maybe something different from what he have in-game now (eg. metorium set). The stats will be chosen by u and like add-ons requires BS to add. EG. Adding 200 luck to my custom armour cost 20k bs, adding +5 to my armour needs 10k bs and +7 20kbs, naming your armour cost 5k bs.
5th suggestion: Make name-changer available to everyone but at a cost, even if your a member(Paid by bs)
6th suggestion: Like per 1000bs u spent away (trading/gifting not included), you get free 1mil gigas and when theres no more BS in game, gigas will be very valuable.
7th suggestion: Make coin items in shop payable with gigas and BS and durations like Permanant.
8th suggestion: I had one more but I forgot ._.
Edited: 8th was Transferring items, gigas or coins from low to high server at the cost of BS
Hope this helped!
