In my opinion it will take a lot to dethrown Bitcoin. Even if Bitcoin doesn't have the market cap it will still be the one that's talked about.
I dissagree, as you see the bitcoin is falling and soon ETH will be the number one on coinmarketcap, it mean that trands has changed.
Yes the trend has change but looking forward to the news circulating online, some governments will adopt bitcoin has a commodity nor currency and they are very serious on studying the blockchain. Bitcoin will have an impact if countries will create their token.
