Founded by Charles hoskinson(a very clever man) and with the slow release of Shelly and a debit card coming out I think this is one for a long hold. Only hearing good things.
Cardano is in really strict competition with eos right now. There is a lot of problem with debit card and you should not expect a lot from there and remember about visacrest.
Shelly looks interesting by i never heard any ETA when it will be released.
