[tensiones]

hey, I have created the second account, and I have leveled up the char there and I would like to sell it, but I got this message
"A minimum of 5 coins is required to sell via the trading system, you have donated for 0"
so from my first account, which is premium, I have sent/gift coins, 6 coins because one was deducted to have 5 coins for trade but I still got the same message! which I later read somewhere that those coins must be donated, but u can only donate for 10coins btw..
so I said like nevermind and I am trying to gift those 5 coins back, to get 4, but I cant because I am not contributor rank :/
you really need me to sent you another 10 euros? where was the information about all this in a first place?
or how should I deal with this situation?

Being able to use Trade to sell is a Premium account perk and sending Coins doesn't make an account Premium.
