TRON is also good, it is also worth to invest. However, I recommend investing long term in Cardano, Cardano is better than TRON. Cardano has a well-developed, highly scalable team. Many experts say that in the next few years Cardano will grow very fast and compete with Ethereum. At present, Cardano is very low price, if you want to make a profit in the future then you should buy Cardano now.
