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.
You decide what you need to do, but I want to ask why you want to sell Ethereum at the price of $ 400 and transfer everything to TRON. Do you see more potential in him ?)
