There's a lot of people who are hyped into mining are now suffered big time lost on their investment on GPU, CPU, HDD and ASIC mining, I bought Dozen of GPU but a month later, GPU mining collapse. For me much better to do trading and Masternode mining.
Witnessing is like masternodes. Different tech but u still earn with funds
Gulden witness is a completely decentralized solution while masternodes is a highly centralized technic, that's the big difference.
Strange this tech has not been promoted on media sites to garner more attention?
Maybe not the media sites that you are visiting
FB, reddit channels, Medium articles are written, linkedIn, slack channels, twitter, several telegramgroups and a little bit of Bitcointalk is used. But no paid advertorials if that is what you mean, There is no money for.
