Yes, yes, yes... I'm sceptical, very sceptical.

I mine 25 XDN per day : how many days for half a million ? 20,000 days ? 55 years. LOL (or not) !

With all this money, you will be able to develop a beautiful, simple, efficient miner for Ubuntu (nVidia GPU, DEB packaged) :-).

Edit :
The miner in the wallet work well, but for security reasons (bugs in the multiples miners configurations trials) my wallet is not on the machine who mine.
