hello i do not understand anything from this coinswap is it obligatory? so I do not want to change, is there a problem?
Eventually the old non-ERC20 ETHD will become worthless because not supported anymore by the developers so yes, no point in keeping them.
Dev sold so many coin on EtherDelta

Yes and will sell more once listed on more exchanges.those are ethereum buys on etherdelta right?on other exchanges they will be btc buy options so more distribution
Yes only ethereum buys on etherdelta, so the price you can get ETHD is lower compared to the price you can buy it in novaexchange or coinexchange.
I agree with you it makes much more sense for Ethereum Dark to be an Ethereum based token.
Dev made an announcement that ETHD will be listed on new exchanges, and as you see today the value is low but after it get listed it will PUMP up once more like before it reaches ore than $5+. We expect that it will hit ranging between $10 - $20
Do we know which exchanges?
I think Ethereum Dark has now a big enough community to be able to be competitive for Binance coin of the month.. just saying...
