Considering Cardano ADA gained around like 10X in just weeks after the ICO you should have probably waited for a retraction.
In my opinion its a good choice. Cardano is basically a way better version of Ether in its baby stages. Running block chains in parallel to resolve scaling issues is the best innovative idea out there. Cardano is one of its kind plus the team behind Cardano is hands down simply put the BEST.
Cardano
Ether
Neo
Qtum/Icx
In that order for me.
