How much would they cost at exchange?
Last week it's worth around 50 satoshi/zipp.
If you want to trade with this user, I suggest you to use escrow.
Which exchange are they currently listed at? I have a few of my own but I won't be putting them up to sell for as low as that.
anything-e.com , I don't know this site trusted or not, but i've done 2 trade there. You have to verify your email and phone number before request payout, and minimum payout is 0.01 btc.
Never heard of them, I guess I'll hold on to them until they get listed at a good exchange since I didn't invested anything in them, I got nothing to lose. Thanks for the info though.
