There are 3 miners, wolf's, claymore's and yam. Yam is going to release update soon.
I have no idea about that miner but I do know that I wouldn't trust a Newbie to point me to download anything. Beware.
I am also using that miner for a while now, didn't see any problems. Fee is even less than Claymore's miner.
Everyone can make his or her own risk assessment, but if I were downloading a binary (at least I assume it is a binary) from some unknown source I would at a minimum only do it on a computer without any data I care about, and definitely no wallets (XMR or otherwise).
It might be just fine, or it might not. Pretty hard to tell.
Good point, though i am using it on my rigs that hold no data whatsoever, so yeah, people should stick with known stuff on private computers.
This isn't confirmed though is it?
Nothing yet confirmed, maybe you could try to PM moolah on irc. He is in the #dogecoin and #bitcoin channel.
