Hi, I think that at the moment you need to invest in Ethereum and other Altcoins. In the future, the Altcoins will be able to make the most profit.
Nope ,as you look in market bitcoin is highly fluctuated than altcoins so I think it's not enough to defeat bitcoin. But there's a lot of time to recovery for that ,we can't predict the future of each coins we're just hoping that there will be more precious benefit at the right time.
