You are right, TRON has a total supply of just over 100 billion tokens and at the time of writing, about 71.6 billion of these are in circulation. The Tron Foundation was given 34 billion, and a company owned by Justin Sun got 10 billion.
It seems like that justin has been starting to sold his tron to the market. The growth of tron hodlers didn't mean if this company was good. Tron was lack of hype. it's also having so many complaints on its development. Acquisition of poloniex exchange site was not giving a good result as it's still become a small exchange site right now. The golden age of polo can't be repeated again.
TRON only has 300 thousand holders that continue to grow.
The growth of tron token holders didn't make the price of tron increases. It seems like that tron was a very bad token to be used as investment for now. The development of tron was so bad. I rarely seen a big news related to the tron platform. I never heard justin again. Where's he when his platform was not performing like another platform?
