Here is my own investment advice but not to be taken very seriously because anything can happen in crypto space...
1. Bitcoin Gold
2. Bitcoin Diamond
3. Bitcoin Cash
4. Lightening Bitcoin
5. Bitcoin Private
I seriously can't hold any other bitcoin fork aside BCH, even though currently I'm not holding it for long term. I observed you mentioned mostly Bitcoin forks, the fact that a coin is forked from BTC doesn't mean it must be a long term project. Aside ETH which occupies a bulk of my portfolio, I'm holding LINK and a few other alts i consider gems.
