Ok, so you all know how we can trade items, for other items in the Market Place, right? Well now, we can trade coins, along with the items we would like to trade!
There will be a sign saying ‘Offer Coins’, in the bottom right corner, as you can see in the picture above, where you can put in the amount of coins you would like to trade!
Have fun trading coins!
