This project makes any coin an anonymous one. Unfortunately, this is not nearly as useful as it sounds. They do this by allowing any of these coins to "fork". When a fork happens you are basically creating a new coin that is a carbon copy of the old one or has added features. This means that all the benefits of the old coin no longer apply, including vendors who accept them, exchange listings and notoriety.
While it's possible that popular projects like Bitcoin would want a fork to add privacy features, it seems unlikely. At best this will simply divide users, and it will weaken the project. This makes this coin's best "utility" a not so great feature that many simply will not get behind.
If you do plan to make a Hexx investment though, you will be able to earn some passive income if you run a node. Nodes act as the relay for private transactions, and those who run them are paid for this service. How much you get paid will depend on the network itself and how many other people are actively running nodes to dilute the reward pool. Each reward will also be subject to a community tax of sorts.
This fee is used to fund the development of the project and to pay for things like exchange listings, which can be very expensive and often stop good projects in their tracks as they have no real funding plans in place. Here at least, it seems that HXX has thought ahead, but it may not be enough to save them. In most ways, they're otherwise mediocre.
Investors looking to buy Hexx will need to do so on one of only a small handful of exchanges. This is, unfortunately, no the best situation for trading, and to make matters worse, much of that volume is confined to just one exchange and trading pair. This discrepancy can make it very difficult for users to actually complete a trade outside of these very specific parameters. While there is a volume in other pairings, it is quite small. This means that if you wish to trade inside these pairs you'll need to be careful. It's easy to overpay for an asset using these low volume pairs or exchanges. Bitcoin is the most viable pairing here, but there's also a tiny amount of volume in Litecoin and Doge if you want to try those.
The developers have created installation packages for Windows, Mac and Linux based operating systems. You'll need to navigate to Github in order to find the appropriate file. Be mindful that you choose either 86 or x64, and that it matches your computer's current OS configuration. Use PC info to tell you your system type if you're not sure which you have. Be aware that you should only use the newest version of the wallet as there could be some issue with older ones after this coin forks.
