All those you mention are great options that not only incentivize early adopters but also continue to demonstrate the versatility using the Steem blockchain brings to projects of all types! I like the fact that they included a Steem account for those who participated in the Kickstarter. This provides a great entry point to the Steem ecosystem and community.
Great reply, good insight, growth comes from places we may not expect, I’m a steem fan! :)
