i buy 1000 ethd by coinexchange.io , i no sell and hold . coin of my lost it if i don't swap ?
You will lost all if you don't swap. Coinswap deadline is 11/10/2017 and the old ETHD will be done with as nodes will be stopped. I think you don't swap, sold it on coinexchange and buyback new ETHD, it will cheaper for you.
