bull run? well not yet, but it is nice to see the market is recovering especially bitcoin and about TRON I guess it's a good investment for long term.
I consider bull run is starting if I notice most of the coins in the marketplace were able to gain bigger increase compared to what has been happening right now. That needs enough time to develop a better demand, and only one thing that could trigger more buyers to buy and hold crypto coins was they're relying on the top btc price. Ethereum price also will follow once btc is generating more profit and become so expensive.
