What bothers me about Cardano is their max supply which is really high. I am afraid it won't reach 3 digits value. I hope I am wrong though because it looks very promising and I really believe in their project. I will hold some for the next few years and see what happens.
it wont get to 3 digts value for sure... but 1$ and higher is like ethereum at 300$
it can be as good investment as in ethereum when it was 60$
the value of 1 coin does not matter, what matters is what amount you invest and what is the marketcap when you investing it
