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.
Everyone has their time to shine. Many also said that bitcoin will not reach this X number because it is impossible, look at what happened, they did not expect the "bubble" to grow bigger again even though there is no popping. Maybe it will not reach that same height but it will be reaching higher than expected.
