My perspective is still bitcoin , bitcoin is decentrelized coin and by the marketplace demand it determined the price of bitcoin that is why bitcoin is stable , and on the Ethereum , eth is one of the best alt coins despite the price of it , eth is absolutely on the second place. And if you have a money to invest make sure to invest the half of it in eth and the half of it in the btc , its more worth it though.
Maybe, I see ETH follow the trend of bitcoin. But ETH should perform like bitcoin did last year so we can say it is the next bitcoin. So far, I dont see its movement to consider its the next bitcoin. But who knows, maybe in the next more years.
