Sorry  I still don't  understand  the real potenciality of  some projects  for  example   Ardor  and  NXT  and  IGNIS, and  NEM

I  saw  them  here   a  couple of times  and  everyone  said ''Invest on them, thy are   good  projects''

Can  you  please explain me  what   do they make?  

As  I have understood  they are project  comparable to ETH

What  makes  them appealing to  me  is  that they  have their  own  [Suspicious link removed]pletly  separated  from the bitcoin blockchain?  

So  should  they be valuable?

Please help   I can't understand the real potenciality  of  these projects  

Please help
