This is the one ICO that I am more confident about, Nauticus Blockchain. In general, I am very buoyant on ICO as the new preferred crowdfunding method for startups.
Back on Nautical, check more info here,
https://www.nauticus.io/I think it is a legit business based out of Australia with already over $12 m, and featured in many media. The founding team also very proactive on various meetups and interviews. I like the idea of on-the-fly exchange and payment solution plus the mining facilities that will be set up in 2019. This will definitely be adding value to its tokens. Please do take some time to research on Nautical, still another two weeks before the token sale ends.
