It's true that some Altcoins might try to reach bitcoin technically but it's never possible that any coin of any kind can challenge bitcoin even the almighty Ethereum is still second to bitcoin even with it's stands ever since created, bitcoin is the root of all cryptocurrency so it's obvious that you can't bitcoin the root, there is a law in my place that says as it is outside so it is inside, relating it to bitcoin means that the more altcoins seems to be growing the more bitcoin grows beyond reach.
Bitcoin is king we can say that, no coin can challenge bitcoin even in price.
Not many altcoins are technically better than Bitcoin, they are all upgrades of Bitcoin as you have written since Bitcoin is the root. It will always remain on the top and Ethereum has been in that position of second since 2015. Other altcoins did try to challenge it but were not able to take the position. The problem with altcoins is that not all of them are here for the long run and if we talk about meme coins then it is a phase that shall pass. The current hype will not stay that long as there are others in the pipeline like the mobile tap meme coins.
