@Mandoy,
".......signature campaign and trading."
You are right!! signature campaign & trading. Trading,Nobody like to engage his or her time on something which is difficult to trade or sell out at the right time. But, don't forget that back in 2003 nobody believe that bitcoin will gain such popularity to the point that both those in govt house,media ... started talking about it.
Somehow, i think some group of people ( who saw the vision & the benefit of what bitcoin will become in future )kept the ball rolling back in 2003. Today they've passed the ball onto us.
Same applies to every other precious material's around us. inotherwords, the value of a thing is determine by the interest & curiosity of the masses. such curiosity leads to interest.
When it comes to mining copper, i've done series of research and found out the need. The problem is that a major part of the local seller's who are invole in selling & buying of copper donot handle the biz in such a way that it will give room for a further growth within the market.
So, i think a team of people who can create such curiosity is needed. And, this can be accomplish through the use of a virtual currency such as bitcoin.
Just immagine for a second what will happen within the bitcoin & copper circle if, 30% of the existing seller's start's paying their local customer's in btc in exchange for their copper!
Thanks
