I've indeed been thinking about this: how to grow wisely with all the new opportunities created? I'm going to focus on STEEM first, still, then CreativeCoin, second, and then I will curate some posts on SteemLEO - I'm not someone who will post content on that platform much but I can still grow my holdings by curating - investors must find a way to make these tokens valuable at some point is my reasoning ;-)
I'm loving the phase we're in right now - lots of growth and experimentation, and as with all crypto, maybe only 5-10% of the projects will stand out in the end and thrive in this ecosystem. Just pick the ones you think will keep on attracting Steem users or better yet, users from outside, and stick with them.
