Tell me how many you wanna sell.I am a trusted buyer.I can pay by paypal,bank transfer etc.
If you want to buy with fiat then you need to do some verification that some exchanges require, I'm not sure if you can buy directly dogecoin with bitcoin but there are some alternatives.
First of all is coinbase that accepts bank transfers (of course if your country is accepted by them), then after buying bitcoin you have to exchange in dogecoin. Also bitsmap you can buy there through credit cards (if i'm not mistaken)
