Other crypto auction sites where you don't enter contact information usually require you to fund a "bidding account." Darkbids doesn't want to hold your crypto and we don't require a bidding fund. I don't trust other people with my coins
The site is a complete marketplace and not just an auction, if you find non-auction products you wish to purchase you can do "guest checkout," not join the site, and not enter as many details.
If you check our privacy policy https://darkbids.com/privacy-policy/ you will see that we really don't care what contact information you put in your account page, we just want to make sure your items get to you
Edit: If you have links to other public crypto auctions please feel free to post them, I won't consider it shilling. I think it would be great to do some comparisons.
