Because it is getting hyped in every cryptocurrency forum. That's how the trend in the altcoin market works, people pick an altcoin (in this case, TRON) to shill for a couple of weeks, and all of a sudden it gets a good pump thanks to questionable news that resemble a marketing campaign, FOMO money, and investors pouring millions of dollars expecting for a return of investment in the long-term.

Honestly, TRON is overvalued, it's a "cryptocurrency" with no actual product since 2015. But given how the market has been completely irrational for the past few weeks, it could be a good invesment since altcoins keep going up, just be ready when the dump begins.
