Two altcoins I would recommend you for year 2018:
1. NEO - in my opinion most undervalued coin ATM. Right now it is at $60, I expect it to be at least $150-200 in 2018
2. Cindicator - although it had some recent pump because of PBC, they have a good idea and a dedicated team. Couple of good partnerships and I can see this project at $300m mcap.
I do not know why you think that the Sindicator has much more prospects in the future than other projects. Perhaps it is better to call such as Centra or even Soma. but about NEO, there are a lot of questions, because I also participated in this project, but I do not know what will happen next,
