ADA is one of a kind...
written in haskell from scratch and fork resistant
backed by academic research
watch the team :
https://iohk.io/team/11 people that only make research work + 25 cardano developers + 5 wallet developers + 5 ethereum classic developers (projects will run with cardano) + 4 devops + 2 web developers
and more people in project managment etc......
this team is unstoppable, and even if someone wants to make some competitor, it will be very hard because cardano is 2 years ahead with all this team...
its actually older than ETC .. its a fact
ADA is going to be in ATM's
they are working on virtual machine with runtime verification (read about runtime verification they are VERY respectful) they worked with NASA on their system
proof

and many more good things....
i am writing it only because many people said yesterday "i've never heard about this project, what is it? is it a pump and dump ? is it a shit coin?"
now you decide if it worth the long term investment
good luck
