Just sell your DASH for BTC and then buy UNO on cryptsy...
Send the UNO to bittrex or cryptopia and sell back for BTC. If you want DASH in the end you will have to use bittrex as cryptopia has no DASH market.
I have accounts at all of these exchanges that I have used for a long time, 6,000+ manual trades on cryptsy in the last 2 years.
I would like to say I'd be willing to assist you with this WD for 1% of the recoverable amount or something but if the UNO for some reason gets stuck coming out of my account there is nothing I can do and no way to predict that. I currently have a GLD withdrawal stuck for over 30 days so I feel your pain. But I have had maybe 30 withdrawals work since these withdrawal problems started from me arbing DOGE.
IMO you are looking at about 50% loss to get out right now..
I knew this way .. but I dont want lose 50% by the way cryptsy will withdraw finally. ...
So what I mean rather than lender money wait his money ... he can wait cryptsy to withdraw almost need less than 30 days
But I am really no patient now with cryptsy
