NLX was created to take advantage of a new privacy-based Null protocol. The developers believe that this protocol allows for a superior level of privacy that has previously not been possible with the options which are currently available.
This method can completely eliminate transaction linking by using a destruction and then a reconstructive method to create these transactions. Most other anonymity based cryptocurrencies only obscure the path, but they can not delete them entirely.
Investors should be cautious here, this is actually a "remodel" project of GPU coin, and while this can sometimes lead to gains, the project may fall through just as easily. The team is working on forking the project to a new codebase, but that update has been delayed, and it is not certain when a Nullex investment will actually come into its full potential.
Investors can only buy Nullex on a few exchanges, and the trading volume is not great. Most of it is tied up on one exchange though, and this will severely limit your purchasing options. Bitcoin is the only really viable trading pair here, as the others have too little volume in them to be useful for the most part. Investors should be cautious when utilizing other trading pairs to make sure that they are not paying more than the fair market value for the coin. With low volume assets, it can be easy to overpay.
If you do not currently have a Windows operating system, then you are sadly out of luck for this coin. There seem to be no versions available for Linux or Mac. The developers are working on an Android wallet, but it is not yet released. Make sure to always create a backup of your wallet file in order to protect your investment. If your host device is damaged in any way, this will be the only way to regain access to your investment.
