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. Ethereum processed thousands of transactions daily and their blockchain is very powerful. Millions of investors are desires to collect as many ethereum as possible and investing to this altcoin will be your brightest decision in the future. Once BTC multiply the price to 10, ETH will surely follow.
