If I had extra cash to put into the platform, I'd invest into the Steem, not the (SBD) Steem Backed Dollars as, not only would you get a lot more for your money right now, but on the long run the value of it will necessarily rise well above the SBD, several multiple times... ;)

Otherwise, I'd sink it into other Bitshares based platforms, such as the Bitshares itself, EOS, the Sovereign HERO, Zephyr or even Eristica, coming out in 2 days! ;)

Namaste :)
