I am holding since 0.12 $ so can't complain but I think it is overpriced now. They actually don't have a working product, it is sitting in the top 5 based on pure speculation right now.
Cardano is going to be used for enterprise solutions such as certificates on the blockchain, been looking at an ICO planning to do the same but now I'm doubtfull about investing really. I got high hopes for Cardano even though I sold long ago at 50cents.
