I accidentally fell into 2 pumps. I bought TRX for 300 sat. right before the pump to 2k sat. The second one was CND for 850 sat. in 2 minutes before palm beach report.
I believe a good bet for 2018 is SCHT. It'll be launched by a product company and their project has a good chance to rocket.
So the coins seem worth buying, because after going public, they will definitely bring profit.
Their web-site looks quite promising as well:
