My fav one so far is ARtoken... I like how they work so far (the company who is behind the project, called Cappasity, they've already done a lot, so you can really see the work progress)... I also think their goals and concept look realistic
they are really cool!Theyre doing one of the first crowdsales which is fully registered with SEC..
Actually, this ICO has just started last week!
