@daneshbaetabrizi thank you for your valuable mention, i believe there is enough space for similar technologies in blockchain to evolve similar to how ebay and amazon two companies are dominating the market.
How ever Syscoin is coming up with an addtional feature to accept transactions with Bitcoin & zCash which bitbay lacks... Let me know your thoughts... :)
That would be a great upper hand for Syscoin! Honestly, the more marketplaces the better.. this triggers competitive advancement and would be in the best interest of the over all community. I would love to start selling products on the side and have a decentralized online business.
