I've been into some early-stage alts. My brother is looking to put up a little money as a trial run and has asked for some initial places to start (obviously, he'll be doing his own research). I may suggest a few alts and am interested in the community's thoughts. I typically review ICO listing sites (just posted a list of ones I like, https://bitcointalk.org/index.php?topic=2680105.0 ) - any (serious) thoughts on 1. what alts you think have highest return potential, and 2. especially if they aren't listed on the usual ICO listing sites like I'm using; what other places to find alts for sale?

PS I'd love some actual reasons, none of the fanboi "it's all going to the MOOOONONNN!!!!"   garbage please.
