Yep, Steem and SBD are two of the best performers right now.
eBitcoin and Astro have also been very good for me... but these 2 are much more underground. Still, with such low supplies, I'm holding on to both... and buying more whenever I can. :-D
PS: The only way to buy Astro is through EtherDelta... and there are only 7.000.000 of them. Be quick... or be ready to pay more! Beware, 'cause Astro will probably be considered a Security... so, you know what that means. I hope. :-D
