Well, we know imc lock 1:1 trade because of gold seller.
I was play a game name ‘Firefall’ ,Dev of that game also hate goldseller.(alot)
What they do is they make a condition for player to make a 1:1 trade.
The condition is
“You can only trade with the person that you added into your friend list for at least 7 days”
So when you want to trade something to your friend, you have to add him to your friend list and wait for a week to trade with him.
The good thing is after the trade is enable, you can trade all you want with that person.
But it can be very annoying when you want to give item or money to someone that you just met.
What do you think?
