Why don't you put the premine in like a bittrex escrow and have it released back to the Dev by bittrex on a pre determined schedule. That way the dev gets his funds needed to pay the bills and people get the assurance that the premine will not be dumped the first time the price goes up.
This is EXACTLY what I was thinking, send to bittrex, let them have it for awhile. This will prove to them that you dont want to dump it.
Send them almost all of it. And tell them you only want it back in certain parts at a time. For certain reasons. But just to get it on their exchange tell them that youll send them 19% of it for now. And if they don't agree with why you want pieces of it back they can delist it before they give it back to you.
So the deal goes like this.
1. Bittrex I will send you 19 of the 20%. You will send it back to me within 48 hours at anytime I ask.
2. I can ask for it back in pieces or in whole. Then if you think I'm up to something you can just delist it within the 48 hours you have to send it back.
Very simple agreement. They are basically just keeping it in escrow, and they can prevent you from dumping it because they will stop the sale of it before you ever get it back.
Simple as hell. Am I missing something. Explain to them that this is a very important project as it may be able to stop ddos attacts effectiveness in the future. It is huge. That's the reason for them to go to the trouble of doing it for you.
That is your selling point. Sell THAT to them. This is an important project and many people are mining it and need somewhere to sell it or it will die. Bittrex can be a part of making the very needed project a success!!!
That's why they will do it.
