I get your concerns and those are also my thoughts about Neo. I believe it means that they just had to push the pause-button, so I think it is all temporarily. I will check the status of this with the people from Neo, since they have an event in Amsterdam on the 13th of Jan that I will attend.
Those 'not top 50' coins are a good starting point, but of course there are a lot more interesting projects. Make sure to let me know when you found a different gem ;-)
BTW, I just posted a more detailed update about my cryptocurrency portfolio than usual. Maybe it is interesting for you to check out. And if you do, let me know what your thoughts are!
Cheers!
