I regullary invest in TRON and it is one of the key part of my portfolio. There are so many advantages with TRON, one is the most important for me - it is much cheaper alternative to Ethereum and ERC-20 tokens. The TRON is scalable, with high speed (TPS) so you send your coins almost instantly. What is a key part for me is that they have zero transaction fees. As it utilzes POS consensus it offers nice yield and also it is more power efficient. If you are longtime hodler you can get some free tokens which utilizes TRC blockchain via airdrop. The acquisitions and new projects by TRON make the company one of the fastest innovator in the field.
The main problem is that there is a controversy about the whole project and its CEO that he is not keeping promises, plagiarism, some technical issues (DDOS attack) etc.
Overall I still belive taht it is worth investing, generating yield and wait for some shift from ERC-20 to TRC-20. At lest TRON should be part of the portfolio to diversify.
