I'm confused how you get people to remove their sell orders. For example, if I have 1000 coins that I want to sell for x, are you going to somehow inhibit my ability to sell them, and only allow me to buy instead?
Any sell and buy orders we talk about are our own ones, the sell orders we have set the minimum price (anyone who buy higher or sells lower would make a loss.
Remember, the coin is premined meaning that we control the supply.
