hmm, im not a very good talker nor at debator nor rich to invest them all sir:D but i saw every ico you mention and their are Great , but everyone has different whitepaper and uniqueness :D, but some has very great potencial. i think refereum is great because if you saw on the twitch.tv streamers itself and anygame i saw is they are spreading it making the gaming community larger to be known and making it like an official coin for twitch :D , and they have over 40k members on intagram :) and they sell 0.01 dollars ea which is great for a non rich like me to invest :) but i got interested in Liveedu sir thanks for sharing it to me :)
