I always thinking high for the Ethereum before that it might surpassed the Bitcoin but after the latest bearish and after this current Bitcoin performance I don't think that any Altcoins can beat the Bitcoin anymore for the number 1 spot. There are lot of new platform that emerge in the market because they don't want to use the erc20 platform anymore so I suggest to stop thinking about dethroning the Bitcoin because $26,000 ATH is very impossible to any Altcoin to beat.
It's because Bitcoin is the most famous of all coins. Anyone could offer the same function Bitcoin could offer, but no one can beat the community being established that supports the whole system. It takes a lot of years to be able to get a strong support system. Before someone can dethrone the value of Bitcoin, it has to undergo a lot of interest from the mainstream media. Bitcoin is still not in its maximum potential, there were still big number of people who has to enter and come in to this digital currency. Once most of the people get the whole idea of Bitcoin, it will continue to rise.
