I am Already a Gem Seller! I top up Gems for Players on Game Clash of Clans and Clash Royale! But the Problem is I cannot Top up Gems Without putting money in Top up system First! And it Seems impossible to do Via the Current Middleman system which is only dedicated for Buy-Sell For Accounts , Producs . Not for Top up Recharge of Gems! So i Suggest For A New Middleman system for Gem Transactions!
We are an account marketplace but we are trying to adjust to fit peoples needs. Anyway this has already been discussed, approved and being implemented.
