If someone paid 2800 for this last year that means they forgot to renew ,so I would say sell it back to them for a couple hundred because I don't see much value here I see better .io domains dropping, reg fee , if it was singular , I can see a brand possibility don't fall too much for the recent hype in .io unless you know its a good one ,and the good ones wont drop
Still have this? Might be worth keeping a hold of or finding an end user for. To help you out, I can really see this becoming one of those .io games (like starve.io)
