These are very potential altcoins in the future. Altcoins are the places that generate higher interest rates and profits than Bitcoins. The altcoins you listed above are highly regarded altcoins like Zilliqa and NEO.
I don't think that there are very many alts or projects in that area with any real long term value. Most of it is just smoke and mirrors to dupe investors out of their money. It's not a new thing either. This has been happening in the alt market for years and years now.
