--- WARNING ---Do not mine at their official pool (
http://pool.dopecoin.com). I used to mine there and I lost my coins (about 360,000 dopes) when I requested a manual payout (no Txid either) to my AllCoin account. Sent an email to support two weeks ago, but never got a reply...
Mark my words....mine at your own risk there.
--- WARNING --- Mining to an exchange is bad practice. Stop doing it.
Pools and exchanges sometimes have errors/bugs. It is best to mine to your wallet sending out automatic payments every hour.
Just cause a pool had a problem and doesn't respond to support for a week doesn't mean they are a scam.
