Do not think at present something like this is going to happen or at least for next year can be rest assured that ETH will remain the best altcoin if want to stay invested in crypto currency . So do not ignore ETH for TRX else you may not make money .
Ethereum is the best Altcoin so it is not easily replaced by other Altcoin.
today many coins move well but that doesn't mean they will surpass Bitcoin and Ethereum.
Ethereum can rise higher and higher.
so use Ethereum because it will benefit you, TRX will also benefit you, so take advantage of both of them as your opportunity.
