Interesting offer, but i am afraid it's not good enough. The electricity i spent mining ars was more than that. i offer you 1:50 , so 100 UNO for 5000 ARS.
I believe for now ARS doesnt match the requirements for adding to an exchange. we need someone to make new blockexplorer etc. best would be if dev would reappear and take care of his baby.
it may be true there are 4000 premined coins around, but i also lost 1600 on palth. maybe those 4000 are dead like the dev?
I lost 400 ARS that I tried to transfer to Palth but it never arrived. That makes it an even 2000 ARS lost at Palth. At least that covers 1/2 the premine.

I will ask Bynergy.com if they will set it up. It's OTC, but still better than losing coins on something like Palth.net
Keep a watch on Bynergy.
