I'm still mining Noblecoin, but only have around 5mhs.
Difficulty has dropped a fair bit lately, making it possible to stock up on Noble by mining again.
I now hold a lot of Noble and have sold very little since joining the community - I have been buying some recently as well (around 5-6million).
Am hoping that Noble will start moving around when the Marketplace discount is enough to tempt people to buy some Amazon vouchers - the only issue is that with the value of Noble so low, people are vary that a decent rise in Noble value would easily beat even a 30% discount on purchases...
