According to this thread, the Tron Foundation gave themselves 35% of TRON and the "Founder" of Peiwo (who is Justin Sun) gave himself 10%.    So this puts Justin anywhere between 11%-45% ownership of all Tron in circulation.

This means Justin Sun is the first Crypto Billionaire and possibly Multi-Billionaire.
