Yes, If 100k NEM was added to the gold coin then it would have cost much more than the current price. The idea is to sell a physical commodity and support the development of a "Mobile Wallet and a Fast Exchange". So people buying these coins are not only helping the developers raise some money to help fund the side projects but they are also doing a huge favour to themselves and the whole community. In the end they also own physical assets which are not likely going down in value in the future. Infact in 2-3 years when NEM has reached greater heights, these coins will be highly collectible and will carry a hefty price tag. These side projects are really going to define NEM and make NEM standout from the rest of the Coins currently in existence.
