Definitely Electroneum ! Cardano is outdated, if you understand chinese/japanese languages, you would know that they are scam, their volume on bittrex is far less than the total. Cardano's real value should be less than DogeCoin. There is also a rumor that there exist a benefit conflict in their organization that may affect your investment in long-term path.
It's clear you didn't do your research/read the whitepaper. ADA is a solid project with much to offer.
"Less than Dogecoin...." quit making an ass out of yourself.
