Might be. No harm in mining a bit, but i would advise against buying masternodes. At least until the project has gained some traction.

A good exchange with a good mobile app is definitely needed. Best of luck!

Just started mining - I've found Suprminer to work well for nvidia (1080ti + 1050ti) - getting me around 25 mh/s on stock settings. Overclocking doesn't seem to make any difference to the hashrate, so I've turned my OC off for RVN.
