I am in 100% in GNH because I really believe in the company, I really like GOLD, and I think we are in a great play that doesn't come around very often.
Its up to you, what you want to do.
GNH could be $1 in 2 weeks. I dont know much about GBB - but from what I heard its similair in play to GNH. So as Glorieux has mentioned you can stay status quo. If you can handle more risk and therefore more reward then go all in with GNH.
