Marketplace is now being a promising industry. the Ninja platform being the first to offer integrated cryptocurrency payment options, including Bitcoin, Ethereum, and Litecoin, as well as Yoshi coins. very interesting
This is not the first one just to clear your statement.
there are many projects who went first with cryptocurrency payment.
though the project will be the first on having second hand goods connected in blockchain.
Yes, there are same project but this project is very nice because of the fact that it is international and very accesible due to their user friendly app. Hope that they can execute this well so that investors will get rerurn.
