There is a privacy token I'd like to point out, Quantum1Net's Q-coin you help you take a step forwarder from the Internet of Things, by placing you on the Internet of Everything. The project is Quantum Safe with so many added features.
I'm fond to privacy coins but the one that you mentioned, I'm not really familiar with it.
IoT has also been the title of some of the coins advertised before with bounties.
There a whole lot of tokens on the market now which have a great potential. However, I expect ripple to hit bigger in 2019.
Sadly,
