This exchange platform comes from the real Bitshares cryptocurrency project that leads some aspects of current trading, and stock options for payments. However, the product itself is not so much effective in the practical field of trading because it has updated features starting by an undeveloped web page that tends to fail, or load content after various exhaustive minutes. When te content is finally available, it's not what users expect, and besides,the price selection is not optimized to the general value in the market.
There are better options for trading as here you can lose so much both for the fees, and for the options you apply. The site is just available in the web. There is no mobile app idea for future developments.
And finally, the service might result of difficult use for many users as it is not like common exchange networks, but rarely developed.
