Currently, the value of coins are driven by speculation... not many people understand (or want to understand) the "growing" crypto currency. Many people think of it as a bubble or something that will die in a few years or as a short term/highly volatile investment to make "quick" money.
For GLD price to go up short term, more people have to become interested in it. So for us, all we can really do is get the word out everywhere you can. I've been doing it by telling friends, coworkers, families, etc. Many people have gained interest and are asking my advice for mining rigs whereas some have totally denied any success of crypto currencies in the future

I've taken my first steps on promoting GLD by selling a few goods for GLD on here. It was such an easy transaction

However, I'm really looking forward to what the devs are cooking up for the new client.
A lot of it right now is the waiting game for us... and really hoping that the devs and some dedicated business guys who stop by here to spread the word through media and coordinating with firms in Wall Street, etc.
I'm looking at GLD in the long term for when things change:
1. Crypto currency becomes widely accepted = more people interested in GLD = price goes up.
2. GLD becomes independent from bitcoin/litecoin.
3. More exchanges with GLD <-> FIAT trade.
4. Media spotlight on GLD. Possibly something along the lines of precious metal exchange accepting GLD, GLD becoming the new way to invest in physical Gold, etc.
5. More services using GLD to buy/sell goods.
Who knows how long it would be for these to happen... but I'm hoping less than 5 years. Look at bitcoin.. it didn't happen overnight.
