i buy 1000 ethd by coinexchange.io , i no sell and hold . coin of my lost it if i don't swap ?
I am reading thread page 496 so this might have been answered. But since, I have seen frequent similar queries, I am feeling obliged to answer.
Coins @ EtherDelta => New ETHD (Not needed Swap)
Coins @ your MEW (MyEtherWallet) => New ETHD (Not needed Swap)
Coins @ Anywhere else => Old ETHD (Must Swap or Sell. Soon exchanges are going to delist the old ETHD).
