We can go over it again
Miners holding bitcoins long isn't going to affect the market as much as you think. Even if everyone sold all of their coins they made every day that is only 7200 btc a day on average. The volume at mt gox even after their situation is like 30,000 a day. And most people don't just sell their mining coins immediately. Basically the market would continue on as normal, and grow like normal, and you would have your btc on the sidelines ready to hop in at a prime time.
Im not implying that we will create "scarcity" by holding. Or that we will damage the volume to the point of no return. Because we wont. Im implying that we should maybe wait for the community to grow before selling our coins. Since we seem to have a correlation between the amount of people using bitcoins and the price. Actually, the volume goes up usually before a price goes up (at least in stocks). The price goes up because the volume sorts itself out into people that want to go long, among other reasons, and thats when the supply dries a little. They create a price floor, and it happens all over again. The news releases, financials, etc. are what really effect it. But if it is smooth sailing you can look at the technical indicators and watch the natural flow. I dont see bitcoin announcing bankruptcy, or inside trading, or a loss at all, oh wait its impossible to get a physically detrimental situation with bitcoin because it is not one thing. The only thing that can somewhat F*** us out of no where is legislation.
