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.
Just stick with ethereum, if u keep patience to hold your eth you will get a lot profit from that kind investment.. TRON is pretty good too, but i wanna give you advice just stick with 1 coin and forgot about another coin..
Diversification would be better, in my opinion, don't want to put all my eggs in one basket. I have my current TRON frozen in my hardware wallet and converted to TRONPOWER to use it to vote for super representatives using The Tronscan wallet with my Ledger. Over the last 4 weeks, I have spread my votes across several representatives (10+) and receive small amounts of TRON and in some cases IGG tokens in exchange. The longer I keep it frozen the more it accumulates and works for me.
