Blockchain P2P network sharing of unused bandwidth

[Mark226]

First, I'm a newbie here, started studying crypto stuff less than a week ago.
Got interested in it after finding Privatix.io, which uses a blockchain platform for P2P network sharing of unused bandwidth.  Sounds like a Magnificent project.
Took me too many hours just to put a few USDollars into an account; first bought some ETH at Coinbase, and then moved them to MyEtherWallet.  Each transaction charged a small fee.
Now, I cannot find how to trade those ETH for the Privatix PRIX coins.
How to do that?  Cannot find an Exchange that deals with PRIX.

OR,...  maybe I shouldn't choose Privatix?  In this week, I've found a few other websites that allegedly do about the same thing, like substratum.net and mysterium.network and orchid.com.
Anybody here has studied those four companies/websites?  I'm not specifically interested in the INVESTMENT side of this; moreso in USING the service. 
WHERE can I find info comparing these projects?
Pros and cons of each service?
Do you know of other websites that offer a similar thing?

Any advice?  Thanks, people.

Really, people?  Many views, but Zero replies.  I came here for an intelligent conversation.
Looking at the many other posts, though, I see that you'd rather discuss the extremely obscure subject of "What's better, BTC or ETH?"
OK...  sorry to have wasted your time.

Perhaps somebody could point me toward another more appropriate forum?

Thanks.

p.s.  Found coss.io for trading the ETH for PRIX.
