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.
Yes ethreum is currently the best crypto coin to invest into as there are other contenders of bitcoin which are not too stable or popular like ethreum.
