they just take advantage by buying when it is cheap + spreading news = Sell.
That might be true but TheQuin has stated that you will be able to sell back the token to the site if you purchase it from the site. There is no merit in purchasing back what they have sold at higher price .
3 - After the start of the rewards program, will it be possible to sell FUN within the site freebitco.in
Yes. When it goes live on 15th March if you bought from us you can sell back to us.
I personally will not buy tokens that are at the pump 5x higher than the normal price
I personally wont either but given that it has few benefits especially if you purchase it a month earlier than the launch date then I dont see any problem with people purchasing it especially when they are active using this site.
