I have read that BitMit was a good marketplace. I'm unfortunate that it was closed before I use it. Can anyone, who has the experience of using BitMit, please tell me how the product delivery tracking used to work on BitMit ?
What do you mean by product delivery tracking? It was basically an eBay-like site where you could sell or buy/bid things and buy them with Bitcoin. You first send your Bitcoins to an escrowed wallet on the site, and the funds were 'frozen' if you bought something. If you received the goods, you could 'unfreeze' the funds and they would go to the seller. In case of a delivery not arriving, BitMit would have to settle the conflict.
