Hello got few suggestions for future transfer tokens:
token for gold - for example make price 50 000g & add cooldown (2 or 3 months) for that item after buying it
paid token - 25€ - 35€ would be absolutely ok
items bought from trading post will have “sell protection” (items bought from “TP” will not be sellable for 1-2weeks)
I dont know if these ideas can fix any issue that you want to prevent, just wanna help.
BTW: everyone stay safe and I wish you happy new year.
