i am choosing ETH for its absolutely sure profit from it, because it is being used by many project as basic platform of their project. but, if you like to play a little risky play, you should invest 20 % into TRX or TRON like you mentioned above. $1000 = 800ETH and 200 TRX .TRX =Risk
Tron is about to become the decentralized version of ETH very soon, plus it'd be wise to hold tron for the main net launch then buy ETH etc.
