yes i see this on aion, ppl who have money , buy ncoin for example and buy premium 30 days, but is sealed so he can put and register on market, so is easy, and about scams, trust me i see many friends who lost some gold and time with support to give gold back but is 1 time, so if you will scammed again no gold back, and only one solution is to tell ppl to give you premium first, but is hard and price some time is to big, so dats why is very good idea, you have gold, but you don't have money on visa so buy from F5
now is time what will not be like 5 years ago then ppl rush to buy many from f10, costumes premum to, only a small group of ppl will do this, i see only to change ncoin system and hm coin system to be 1 value or ncoin price to be 50% lower per item in f10 and hm to be like now, maybe to create some battle pass add with some goods in game , is very hard
