in my mind, I do not think Altcoin is better than Bitcoin. Bitcoin is the best coin in the market cryptocurrency and can say the mother of all coins. I think Altcoin also follow Bitcoin price movement. So we have to believe in bitcoin and altcoin, we can not depend on bitcoin price invest in altcoin high technology also such as ETH coins.
Of course, no one altcoins, except Ethereum, maybe cannot cost more than Bitcoin in future. It is the father of all cryptocurrency market, and all altcoins price depends on BTC very much.
