Here is my own investment advice but not to be taken very seriously because anything can happen in crypto space...
I think the best altcoins you can invest on in crypto space are bitcoin forks, they are very responsive to bitcoin movement and their All Time High is very good too, one for thing is these coins have their halving coming this very year as well
1. Bitcoin Gold
2. Bitcoin Diamond
3. Bitcoin Cash
4. Lightening Bitcoin
5. Bitcoin Private
These coins have their use cases and they offer better performance compare to their king ( Bitcoin ) and their team are very active as well, looking at the past chart of Jan 2018 these coins ATH are massive, buying now means buying at extremely cheap price, they are jumpy, active , responsive to Bitcoin Movement and their Halving is happening this 2020 as well.
Please do not hesitate to do your own research and go through their whitepapers, these are no new projects, they have proven their existence already, thank you
Well it is indeed right to be sacred at most altcoins when taking into account the number of them that keeps coming up everyday. Contrary to your list, in my own way I find it more welcoming going for other major altcoins like XLM, ETH, BNB and so on than these once you just listed. These major altcoins I referred to, at least to an extent we have seen their ways of aiming for more growth and almost everyone knows or holds them. As these Bitcoin forks hardly have I seen where it is highly discussed and so on. Am not trying to counter your opinion but rather am just stating mine..
