Absolutely ridiculous.
It is a strong project with a capable team, but no one can justify valuating it at over $600M market cap when there is no finished product at all. This is more evidence of a bubble in ICO and altcoins. It reminds me of the ridiculous valuation people give Tesla even though their fundamentals are absolute garbage and price is based on ridiculous speculation.
Overall: Good project, but horrible coin distribution and valuation.
