There is always a level of competition that anyone tries to play but that competition does not give any room for altcoin to beat bitcoin.
There is already a lot of evidence that we can find about bitcoin's journey that has led it to become the best so that it is enough to show how strong bitcoin is in this space.
When talking about facts, there is also a lot of evidence that can be shown why bitcoin can be the best right now.

ETH is indeed the second coin that has a fundamental level but there is no chance that it can bring down bitcoin.
Without us proving this has happened because bitcoin is still the best asset for any time.

Technically, bitcoin is a bit more outdated than altcoins when it comes to transaction speed and fees. It is true, we should not deny it and it is a fair price we have to pay for wanting a decentralized asset.

Currently, only El Salvador accepts bitcoin as legal currency, no second country has done the same. While there are also some reports that some countries are considering adding cryptocurrencies as a payment method like Russia, BTC is not their only option. Besides BTC, they also use altcoins ETH and especially stable coins.

But the truth is that no altcoin can replace or has enough power to compete with bitcoin. Bitcoin is slower and more expensive but the safest and most secure. Decentralization is what makes bitcoin unique and as long as there are no altcoins are decentralized, no one can compete with BTC.

Lets just say into the fact that altcoins were created on trying out to beat up Bitcoin or with those top altcoins in the ranking on which this will really be their main target or goal when it comes into their existence on which this will really be just that a normal approach. When it comes into the talks about being threat then there's always the possibility because community recognition and demand will that having the possibility on having that flipping on which this is really that probable but of course knowing Bitcoin as the Father of all cryptocurrencies then it will really be that hard to believe that there would really be that flipping. Come to think that we've been already decade on this market and Bitcoin do able to maintain its position to be that on the top on which simply means that there's soo much trust and support and the ones who do make out some investment. When it comes to its features then there might be those other projects which are far more better than it but as long it do works then i dont really see any problems and thats why theres still having that strong support on which its proven out with the current position that it do have in the market on which i dont really see that it would really be that easily be replaced or overtaken into that spot. Somehow, when it comes to investment that despite on having that kind approach but still it wont really be giving out that kind of guarantee that it wont happen in the future. Always take up back up plans on which its really that been recommended. Threat or not, there's always that competition and demand will really be that easily switched up and this is that very normal. So always set up those reconsiderations on any options that you can be able to take. So everything will really be that matter on how well you do go with the flow.

BTC simply isn't adjusted to be something like ETH - it's the store of value currently, not a coin to be used for fees other projects, as a fuel of sorts - everybody wants to hodl it and just have more of it, mostly.

My advice is not to overthink things because they won't come true in the end.
I know there may be some people or those altcoin enthusiasts who will not agree with what I said but in the end don't compare kings too much with followers because in the end things like this will only make you dizzy yourself with various kinds of speculation which in the end actually weakens your own confidence in what you did before.

Bitcoin is still bitcoin where they will still be king and altcoins will never touch bitcoin apart from following its movements including for altcoins.
We can see how ETH is moving right now, is this not the answer for you when you see the movement of ETH and bitcoin now? I don't want to suggest or make it seem as if bitcoin is better but the evidence now speaks.

Bitcoin is a unique asset in the crypto world. He was the first, went through tough tests (attacks, prohibitions, skepticism) and proved his resilience. Altcoins, including Ethereum, are developing in an already prepared environment, where bitcoin has taken the brunt of the blows.
Ethereum and other altos are solving their problems (DeFi, smart contracts, etc.), but bitcoin remains digital gold - the most reliable and recognized asset. Its value lies in decentralization, limited emissions, and the trust it has earned over the years. Even if Ethereum or other coins grow, they will not replace bitcoin, but will exist in parallel.
So the collapse of bitcoin due to alts is unlikely. He has already passed the point of no return.

Okay lets just that going back into those previous years on which Bitcoin was just starting up, on the time of its existence then the next new coin that going up next to it will definitely be basing up into Bitcoins features and becoming that something that more better. This is where on the first altcoin creation on which its that trying out to become more better on which we do know that these projects didnt end up on what they have expecting because the main thing or simply being powerful is about on community support because no matter how good your project is when it comes into those technical aspects but still it wont be giving out that guarantee that it could be overtaken by some altcoins. We've been currently existing for decade+ and no matter how altcoins do progress out but still it wont be enough on overtaking up Bitcoin into its top spot. If you do try to make out some comparison into those new coins/tokens out there then no doubt that when it comes to features and utility then it is something that more or better looking that with Bitcoin.

Being the main coin or lets say the father of all crypto coins will definitely be the reason on why Bitcoin do still sitting still on #1. It is that there are people who are that still skeptical about Bitcoins potential.
Now that we are already approaching nearly about on the bull run period then majority of us will definitely be that optimistic about the numbers that would be able to reach out or simply talks about having that immediate action on the time or moment that you do become or have seen up some opportunities then its rather worth on being mindful and thats why you do think up the other way around.
