Who runs coin.community? Why should I register or trust anything on there?
Why use a (seemingly) dead web auction platform instead of just doing an auction here?
Good question. I run it, and while I have been working on the concept for a while I have not really started advertising it until recently.
The reason not to do an auction here is because they very regularly become absolute clusterfucks with people not knowing if the auctions have finished or not, people biding invalid amounts, difficult to keep track of multiple lots etc.
Also the fact that this is a sub-sub-forum means that it's not very accessible to newbies, coin.community has a much more user friendly interface that has the potential to expand the number of people interested in collecting.
The eventual plan is to open up the shop to members too, so they are able to sell and run their own auctions, but there are a few things I would like to improve before I do that. So for now it's just me selling in the shop, which I think I have built a fair reputation here to justify trusting. I am always open to using escrow if anyone wants to.
