Probably the dev's pre-mine. Otherwise, in the spirit of his "I restart the blockchain if I don't like the balances as they are" policy, he would have removed these funds by now...
Your frustration from the decisions that developer takes suggests that this address is belongs to you.
Strange logic. Why would I suggest that the developer should remove this balance while being at the process of blockchain invalidating, if it were my funds?
Would it be mine, it would still be a worthwhile amount, no matter if before or after an 1:10 exchange. No need for emotions then. I'm just slightly concerned because I am very enthusiastic about the cryptocurrency economy, and what I saw here looked just pretty wasteful on resources, with no real motivation. I don't really understand why you're assuming personal motives here. To be honest, if NUD flies, the blockchain switch would be even an advantage to me, considering that I have more NUD on the new blockchain compared with the old one.
