Price drop down:(
Eventually when we have a profitable company, where DNotes will own up to 25%, and a professionally managed fund to support the market, this will be less of an issue. As of right now, we are subject to the demand of the open market.
Something I've seen some other coins do is have a strategy to put consistent buying pressure on the market. Diamond is a great example. DNotes should look at that. One idea that comes to mind is that when the company launches, any kind of share dividends are paid out in DNotes. This means that whatever currency the profits are made in, be it USD or Bitcoin, those funds will be used to buy DNotes on a regular basis and then distribute them. Since the shareholders likely believe in DNotes, they might sell some back from time to time but probably won't just dump them all as soon as they get them. That will have a stabilizing effect on the market price.
The other strategy I've seen which DNotes already does very well (DNotes vault) is to take as many coins as possible off the market. Giving people incentive to lock up their coins in long term interest bearing accounts has that effect.
