For me, I don't think that Ethereum can beat Bitcoin as the Number One in the crypto market
Ethereum is unique while bitcoin has also it's own feature. We don't have to think about replacing the throne of bitcoin.
There were too many threads out there that wants to discuss this thing but just to answer this, bitcoin won't get down by any altcoin or even Ethereum.
bitcoin is bitcoin and remains the first
Yeah it is the first and major cryptocurrency and it's not that so easy to push out of its spot.
