Sale will last from January 15 to February, and in February there will be a exchange.

Yep! Its getting some momentum. Why do you think the ANN page doesnt have more pages? Are people embarrassed to comment on "adult" stuff? I think thats a big appeal to cryptocurrency, right?

Well sex sales, that for sure. If the platform goes online this one dominates all the other ones with much fairer income for models and a faster payout. Win win I would say.

I will never use my coin to spend times with models. Because if this project become a success i will be sad to have spend my coins for a few minutes instead of days XD To be more serious this platform will be powerful just if you invest in marketing. It's like this that you can start in this sector i think.

We call it airdrop but it could be essentially a new registrations promo, like they give live stars' token worth $10 for new members on the platform

Actually it's clearly stated in road map : Q3-4 2018 models, affiliates and user recruiting ,
LiveStars just launched alpha version of the platform, and some of you expect things to go with a speed of light or even faster
A smooth development and smart marketing, thats what will make LiveStars a stable and attractive project on the market among others.

Livestart roadmap is good. Looking forward for seeing platform in Q3 or Q4 in 2018. I am hoping in meantime they will have more partnership that help enroll many models. Would be nice if add VR apps.

The models would not have to pay for it. It would be a marketing expense from LiveStars, a one time thing to get the platform kick-started.
However, it's up to LiveStars to decide about how to spend their budget. But since it's Christmas we can dream a bit, can't we? 

thanks for answers.

How much one LIVE STARS Coin would be worth during ICO and is there are a minimun amount of invest during ICO  ?

On most Erotic-Webcam-Plattforms are amateurs. And that is what the consumer wants. If the consumer wants professional models then there are other plattforms. I know that there are professional pornstars on these plattforms but they are a minority. Free minutes are on most plattforms but the models (with plattform) decide what to do and to show. Free minutes is a good advertising method.
