I think that the Etherium is not a queen, I would rather say of him as the son of bitcoin. When the King leaves us, a worthy heir will remain
BTC will be the always on top and ETH only follows BTC. ETH's fluctuation always depends if BTC fluctuates.
Yeah bitcoin will always here and sorry for ethereum as this will stay next to bitcoin. Although bitcoin and ethereum will compliment each other as the strongest currency due to their pairing in the trading sites and to their popularity. Both are good in long term investment with a higher rate of profits.
