Is is safe to sell ETHW?
No need to worry. The developers changed the chain ID (which is the important bit to make sure replay attacks can't happen with your ETH).
It certainly was a concern, but it isnt a concern anymore because of the update to the chain ID. Their chain ID is 10001 and normal ETH is just 1
