I don't have an idea with most of your tokens. The only coin that I know is TenX. Because of it's debit card that makes TenX as a good coin to hold for a longer time.
Same I would say hold on to TenX as they are the most legitimate of projects on that list. Investfeed has a neat idea too and if they can execute it, having a crypto twitter like that could be big. Obviously not the first one in wins, but Investfeed has a good chance as only Steemit really rivals it at the moment.
I don't know more about investfeed but I'll stay with my choice which is TenX but I'm sure that there are some that can be of good interest too.
I rarely check others who are mostly being hyped by the community and that's why I'm basing it on my own intuition and knowledge.
