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.
