I know I can't convince people of this though the point of the auction isn't for me to get paid, it's to distribute them in a manor that requires the least effort and has low skepticism. Even with the faucet people were pointing out that it could be unfair because there's no way to prove we're not funneling out of the faucet through shell accounts.
I would be perfectly happy buying them on the open market but that's not the situation we're in, to my dismay.
There is also proof of burn distribution like Counterparty did. Fair and not really complicated. Most trustworthy. But brings no money to the devs.
If you want a long distribution (a year or more), you MUST set the price as sharply rising with time.
Of course if you need money you have to go with some sort of crowdsale. But it goes against the spirit of this coin.
But your idea of permanent auction is very bad. You promise to distribute new coins whatever the price is - even if the price is falling. This is destructive, really destructive. I don't believe this promise can be kept. You will be forced to make changes all the time. As a result people will not believe you, they will lose trust in the coin
And the idea to distribute to 7 highest offers is really awful
