I wish I would have bought double the ETH I did when it was at $84 a coin. I got a $100 worth when it was at $84.62 a coin. I intend to HODL it till it goes back up over $400. After it reaches that I'm going to get more TRON with it. I have been using Binance for my exchange. I'm US-based, so I have to buy ETH through Coinbase then send it over to Binance to exchange for TRON.
TRON is also a very good investment, and the exchange can be done, but I do not see any sense in it. Just compare the graphs of these two cryptocurrencies. You will see that Ethereum is growing steadily and faster than TRX.
