Just as Bitcoin is the king, Ethereum is the queen (gives birth to altcoins) and it's the first wife, others are just "other wives".
I will give two thumbs up for this statement and I always believe that ETH will stay no matter what happen just like Bitcoin. These two will always play in the circle and will continue act as the strongest competitor of all cryptocurrencies.
If only we had the thumbs up (like) button

. oh yes both will always be used as a point of comparison because they're actually the real deal. Just as every modern day footballer is been compared with messi and cr7 that's how it's going to be in the cryptoworld. BTC and ETH Will always be the best and first that other altcoins will look up to and be compared to.
