We have to find you some dashcoin users then, unfortunately I know nothing about these - and I would always advise using your VISA card for online purchases as they are all covered with VISA guarantees for fraud or theft.  You might find recourse through dashcoin though I would think probably; you will need to get in touch with etherscan.io support once they surface.

Mind you if you actually bought your coins from the official peculium site then they may be able to offer some advice or assistance - might be wise to contact them too and see what they have to add.
