To be 100% transparent we are not receiving the amount of exchanges we were expecting to see. Apparently people are more willing to see on their failed alts in the hopes they may be revived as opposed to trading them in. I just don't think we have the visibility we need right now which I take responsibility for. I am going to get out and really spread the word and get to converting. We are ready but at this time have 0 pending orders for exchange. We are not going anywhere even if is a small amount per week we are exchanging we are still making progress.
Your probablem may be one of legitimacy. 50% Premined coins are in right now, but perhaps exchanges aren't getting it, and perhaps don't feel as confident in this 50% Premine than others.
Have you contacted Coinswap?
It might perhaps also help if a trusted member of the community held some of the premine to instil confidence. I'm happy to offer my services. I have a portable hard disk so they could be held in cold storage.
I think a better plan, or a more fleshed-out plan would be;
Provided you can verify and prove to the community this is being done, you could dump the altcoins you recieve and buy back up DeleteCoins from the exchange, pushing up their price, and making them more valuable to mine and to hold.
You should need to show that;
1: The value the coins were exchanged for in BTC
2: The amount of DeleteCoins purchased with said BTC
These DeleteCoins could either be added back to the pot, or sequestered for some other purpose. Or destroyed into a verifiable address that can't possibly be spent. Someone more technical than me can explain this process, but I believe it is relatively straight forward to make coins unspendable by sending them to a particular address. This would reduce total supply, and therefore increase the value of DeleteCoin as well.
Absolute transparency is paramount, and provided the community feels safe knowing the premine won't get dumped, it will also encourage exchanges too.
A major step forward would be setting up a block explorer, so we can see where any of the Premine is at any time. This would be a good place to start.
