First of all, you cannot sell the COC downloaded from our website because it is a modified version with a private server, not the original one. Second of all, if Supercell detects that you are selling the accounts, it could result in a permanent ban. So, it is always risky to buy or sell COC accounts. Still, if you want to continue on your own risks, there are hundreds of Facebook groups made for it.
Please note that there are so many websites that claim to trade COC accounts. We have never tried such websites for security reasons. Moreover, selling a Clash of Clans account requires you to provide the Gmail and/or Facebook account linked to it. So, make sure those properties do not contain any of your personal information or data. Also, make sure that you receive payment upfront while making a deal with an unknown person online to prevent fraud.
