Btc will be forking soon.the price is exploding now.virtually all altcoins are down.very soon probably after the fork we will be elated by the sight of green bars which will mark the revival of altcoins.which coins will u invest in after dumping ur Btc gold( as most people I talked to intend to).i will be picking up civic,tenxpay, kyber network, and pvx
As much as people want to keep their bitcoin in order to claim bitcoin gold, I think the best time to invest in alts would be now before the fork as they are all pretty much in a decline, after the fork it is assumed that alts will be back in the green but at what point we do not know, myself I have picked up a few that I have had my eye on for a while but not as much as I would like as i am also waiting for the free bitcoin that bitcoin gold will get us.
I haven't picked up any of the ones you mention, instead a couple that I have gone for are SHIFT, BNT, TRUST among a few others.
