IMO those are the worst coins to invest, try to look for coins with better developers, more activity in their github... besides many other thing, like monetary policy.
Those forks are dead coins.
Agreed. These are pointless forks with no real use-case. It's all about trying to grab some money through association with the bitcoin name.
If you want a good alt, then look for one with a real use-case. Ethereum obviously being a good example.
