According to coinmarketcap.com there are 668 coins on their site all trading. Do they all do something different or are there a lot of copy cats and if so, what do the 100% copycats have value?
Please show example if you can
All altcoins in real are copy cats,LOL

, if you are going to observe their features it came at the same way they will only change few things only but still obvious no originality.
