BitShares is not only an exchange but also your opportunity to spend your Steem Dollars in real life through the BlockPay point of sales system on BitShares. In less than a few weeks you will be able to spend your Steem Dollars in a restaurant near you.

Exactly, and the whole ecosystem will benefit, and make it easier for everyone to use the system.

Looking forward to this.

Bitshares is the exchange for entering and exiting Steem. But also for investing / trading purposes for any extras you would/could make on Steemit., if you decide not to invest in SDM. It is an ecosystem and all can benefit from eachother. The extra important part will be the SteemGo Coin that will be floated (ICO) on the Bitshares exchange for ownership, managing, trading and growing the SteemGo community.
