Do you have any plan to add built in escrow in your platform it is must needed as lots of zip files or other files sold in this type of anonymous marketplace were found to contain empty several times before thats why forcing user to send bitcoin to multisign escrow address will be good feature and more buyer and seller will love this feature.
We don't use escrow. It is a feedback driven marketplace.
The sellers can have demos so you as a user know what you are buying.
Buy only form trusted sellers (see their feedback)
We check the products and trying to make sure the products are as legit as possible.
