To be honest with you, Dogecoin is something I don't know too much about. i do know there is a huge supporting community surrounding it, such as the Litecoin or TRON or Ripple people...but I really don't know too much besides that. I am holding some Bitcoin and LItecoin and I also play around a little bit on Binance as well. Perhaps the fact that Dogecoin isn't on Binance is a reason why I'm lacking too much knowledge or motivation to learn about it as I can't trade it there. I do mine crypto but haven't pointed my miners or pools in the direction of Dogecoin either. I've been wanting to get my hands on some though... :) -Respect
Try vertcoin for mining, are you gpu or asic?
