Massive valuation ($4B USD)

I agree every coin has to start somewhere, but this one is MASSIVELY overvalued at the current stage of development. This reminds me of the bitcoin pump in 2013. It has a good technology, "a story" is created around it, the price pumps, then it crashes.

Having a good technology is just the start for a coin. The real work is gaining adoption and branding.
