Monitoring this thread since after ICO. My two cents:

1. Privatix had a bounty program, so I heard. Then they canceled it. Why? Too many fraudulent participants.
Who's fault was that? If they can't reliably filter their own participants prior to bounty program start, could I trust them in handling my IP?

Rather than admitting their lack of oversight (which is often understandable at early stage), they shifted the blame to the participants.
But if participants were at fault, why cancel the entire bounty program itself? No participants worthy of the bounty? Not even a single one?
Not a single legit promoter who finds the service worthy of being promoted?

2. Too many promises. And one of those promises involves hardware.
Competition is always good. More competition = more options. But considering other crypto ICOs, I must say that the odds are not in their favor.
All I can say for now about them is that they look like a promising team.

3. What is the US patent pending for? If they intend to use this against competitors: for a company that sells Freedom as a Service, I find this rather ironic.

My list is long, I just reduced them to things that concerned me most.
These are just my opinions. I do not claim to know the future. But for me Mysterium still has the greater chance to succeed in this area.

My challenge to the Mysterium Team (if any of them gets a chance to read this):

Businesses are not built in a vacuum. Early communication and marketing is crucial. Ask feedback from your potential users.
Ask them what things they need that traditional VPN simply cannot provide, and how do you plan to address them.
I believe people in the journalism profession need this service badly than most (adding Marta to the team was a smart move, btw).
And these people are generally not as tech-savvy as those in the IT industry.
Write articles addressing common questions in depth. I have spotted a few of them in this particular thread alone, and as of now, nobody gave a reliable answer.
Try to reply to Medium comments. In my opinion, one post per month on Medium just doesn't make the cut.
These may seem trivial, but your end goal with early communication is engagement.
So that when you finally launch the core, you won't scramble just to get more people to use it.
