There are 2 airdorp in the last 2 weeks.
u can join the telegram group of the IOS, i think it is greater than TRON. By the way, a prediction,

IOS will fly to $1 before Fe.2018.
I think its need more than feb 2018 to reach $1, IMHO maybe at the mid or end of the year it would happen. I preddict that it will be correction price after some pump. anyway 10 cent is a good price for a token that have a huge supply ( it has 6,7 B circulation supply ).
