Bitcoin is already in the top, we are blind if we still believe that Ethereum is better than bitcoin.
Everyone might have their own judgement but in the crypto space, majorities judgement win and that's why bitcoin is still holding firmly the number 1 spot. Some project might be more advance than bitcoin but it's the people who will decide and they choose bitcoin over Ethereum.
Bitcoin is a founder of crypto, we can call it like this, and Ethereum is just a second giant, behind bitcoin. Ethereum does not need to take over the first position of bitcoin, and it won't be able to do that, I believe. Maintaining the second position for coming years will be a very big success of Ethereum, I don't think Ethereum investors require more than that.
People like their coins to surpass the success of Bitcoin but that is not happening as we know we all trust Bitcoin to lead the market.
Ethereum is a good coin and this is the most favorite coin in the altcoins market, so you are right, maintaining the no. 2 spot is already a great success.
We just reclaim the no. 2 spot because at once it was XRP which is next to Bitcoin.
