A lot of coin lost their credibility as the devs stopped doing their work, it's really very hard to know who will be the next coinn that will have sucess in the crypto scenario.
I don't think so, as far as I know the credits and the team did some very good progress this year, for example they have worked with several big companies like Lenovo, IBM, Global Tech Sports even Alibaba, so I think Credits will be the one that best among Ethereum, EOS and TRON.
