Name alt-coins which you would definitely not recommend to invest in to your friends, and give a reason why so.
I want to invest in 10x different alt-coins and I want to save some time by ignoring the overvalued ones.
Thank you!

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:
