Okay, there's really something wrong with the windice.io's wallet as per checking the hash.
I see that there's someone who is also looking for the help of an admin on the chatbox, are you that the same guy? The very thing we can do right now is to wait for the admin to respond on that withdrawal problem that you encountered.
Yes. That's me

Since this site was newly launched probably they are are a lot of things to fix to their site and it might be one of that is their wallet. But I think the admin/dev is so busy right now, the best thing to do is wait for the official announcement from them.
Hey, it's too early to pull out your fund, just enjoy rolling your dice there. See you in the chat box there.

Yes I know!

I'm just trying the instant withdrawal. But unfortunately it's not what I am expecting. 5 hours has past and the issue is still not fix.
