I get what you are saying, but you are arguing how you think it should be (pegging dragns to USD) and that is not what is happening, whether or not you think it's fair is irrelevant. If you don't like the way they are doing it, don't buy in, I haven't seen one person on here or on their telegram pressuring anyone to actually contribute. In fact, this is probably the least intrusive ICO I have ever seen.
I personally like the way they are doing it. I invest in dragons with BTC, if BTC goes up before they hit the exchanges the value of my dragons also goes up. If BTC goes down before it hits exchanges, I'm in the same position I would have been if I had just bought BTC and can trade it no problem.
You missed out on the fact that they didn't bother to clarify it when someone calculated it wrongly. I am not sure how many people read into stuff before they invest, but I have a feeling a good amount don't know what they are getting themselves into.
Sure your dragons goes up, but is that really what the company is worth? There is a disconnect that you are not realizing.
