Yes right, maintenance is normal, it usually takes about 3 hours to 6 hours for normal, I am still active using coinexchange.io because trading here is instant and fast compared to others.
Are you still trading on coinexchange? I can't withdraw ethereum out from the exchange until now.
And I'm getting some error when withdrawing it. according to balances tab, this wallet is undergoing maintenance.
Here is the error that I receive when withdrawing the ethereum "This currency is currently halted or in maintenance mode. Please try again later."
How many hours do you think they can fix this?
If ever they don't fix this I put this on scam accusation DTs will see this and including you will receive negative trust from helping this exchange and encouraging other users to use this exchange without any issues as like as you said.
Edit: It looks like their Ethereum withdrawal is undergoing maintenance so I decided to exchange it to bitcoin and now the withdrawal for bitcoin is working fine thanks.
