I just noticed that Cardano's market cap is hanging around $27B. It seems to be very overvalued at the moment. During a recent interview that I watched, Charles Hoskinson basically said that Cardano is years away from completion, which leads me to look at the Cardano market cap with a confused look on my face. During the interview, Charles seemed to have more questions as opposed to solutions for how Cardano will achieve what Graphene has already achieved.
Many people that haven't researched EOS enough tend to argue that EOS is still in its ICO stage and hasn't proven itself yet. Those same people fail to realize that EOS didn't start from scratch. Bitshares/Graphene was created in 2013, then Steemit/Graphene-v2 in 2016, and EOS will basically be using the third iteration of Graphene, so technically, the blockchain tech of EOS got its start roughly five years ago.
The track record of Dan Larimer and Graphene should show a lot about what EOS will be capable of. Steemit/Graphene-v2 has proven that its tech is fully capably of creating a sophisticated decentralized social network which charges no fees and is capable of scaling to the masses with zero stress on its blockchain capacity. That same blockchain tech is the head-start that EOS had during its inception.
Cardano being so early in its development stage, and what sounds like possibly years from deploying something finished, just seems very overvalued according to where its market cap is in comparison to things like Bitshares, Steemit and EOS.
Anyway, this is just my perspective. Let me know what you think ;)
