Interesting video, comes in perfect sync with the advertising campaign!
For a team that did not do an ICO, the Lethean team has shown their transparency and legitimacy. Lethean is a real decentralized VPN project with actual exit nodes that anyone can test today. The full VPN client is around the corner. And if you are a crypto investor reading this, you might just stumbled into a gold mine.

the problem is that many people have lost confidence in these types of projects. there was deeponion privcy and others that have enriched only their creators and that's it. so now investors have become smarter and no longer go to such options for investment.
I know the coins you mentioned are privacy coins. However, I don't know if they brought something new to the table or what their real world use are, if there are any. The main market of the Lethean decentralized VPN are VPN users. There are hundreds of millions of VPN users around the world just wanting to access ordinary content that are restricted in their countries. To protect their identities, VPN users will be using the Lethean coin (Monero-based) to access VPN services. Individuals wanting to earn a passive income through cryptocurrency can share their unused internet and act as exit nodes for these VPN users around the world. Lethean will become the Uber of internet sharing for VPN services.
