No, you can't withdraw those coins after being de-listed
Yes you can. I was told the wallet will remain and you will be able to withdraw indefinitely. Once your balance is 0 the coin disappears from your balances list.
I have like 267 thousand Q2C coins that are still showing in my poloniex account... I know this coin was delisted long time ago but my balance still shows the coins and I can still use the withdraw button,
but the withdraw never goes through just sits there saying pending... Those coin in todays value is worth close to 4k a lot of money for me.. and I have tried to contact Poloniex support but they never reply..
I do hope that sooner or later I can get those coins back and more them onto Cryptopia so I can trade them again.
If they were delisted why did they not remove them from peoples wallets also?
