Yep, i am having the same situation.
It was stuck some time ago but it was working properly since. But it stuck again yesterday.
I feel your pain brother.
I sent a support ticket to Kucoin two days ago, with a screenshot of the failed extraction, and received an email today saying it's taking so long to extract because there are lots of users doing it !
So Kucoin do not have the resources to handle a few users doing the same thing at the same time, what sort of Mickey Mouse® exchange is this ?
Lol. I was asking for a Kucoin referral code few days ago but my friend told me there isn't a referral system anymore. So is it really working or the referral system was only good during the early stage when Kucoin was still doing marketing?
