Many, especially newbies, think alts are faster profit without much risk.

Whereas in reality, it's totally not true.

Only BTC has that much stability to go forward for many years to come without a nerve.

Op bitcoin is not threatened by any altcoin, for you to say bitcoin is threatened by any coin it means the coin is equivalent to more than half of bitcoin current price probably close to bitcoin, then the battle of becoming the most valuable crypto can be drawn. But since there is no coin that's close to 50% of bitcoin worth, all cryptocurrency are very far from comparing  or seeing them as threat. Ethereum which you mentioned is no where close to the price of bitcoin irrespective of how long it has existed in the market,  that shows that it'll be difficult  for a project to pump out of no where to stand as a threat to bitcoin. Aside price of project the reputation of bitcoin is far greater than any altcoin or shitcoin in the market.

This kind of question will only appear in our minds if we have doubts. This often happens to newbies, but I understand because they are still learning, and so I answer this with NO. Altcoins have nothing to do with Bitcoin because they are different in purpose in the first place. In fact, even ETH can't defeat Bitcoin. How much more with these new projects that haven't established a reputation yet? Too far from happening, and that is also because Bitcoin was created with something special. That is why it remains the king in the crypto market.

And those who always think that end up on the wrong path; some of them end up lucky, making large profits from altcoins. Why do most of them always end up losing the little they have invested? Altcoins are for short-term investments and are not to be held for the long term. Even for the short time, it's too risky for you to invest in them without keeping a close look. Bitcoin is not risk-free, but we can hold and sleep with our two eyes closed, knowing fully well that it won't collapse.

Of course. But most people don't understand this. They believe everything's decentralized, when in fact, it's not. Altcoin developers usually use the term "decentralization" to help attract investors into their projects. But at the end of the day, altcoins are no different than centralized Fiat currencies. At least most of them. We can see how so-called DEXs (decentralized exchanges) and "De-Fi" (decentralized finance) platforms are often hosted on centralized servers with publicly-known developers/founders. They become easy targets for the government.

Truly-decentralized crypto projects like Bitcoin are a rarity these days. If this keeps up, BTC will remain the only decentralized cryptocurrency in the world. It's not about convenience (low fees, fast confirmation times, etc), but rather security, reliability, decentralization, and censorship-resistance. Wasn't the whole purpose of crypto to beat banks by bringing "banking to the unbanked"? This means no middlemen of any kind in the system. It's why altcoins will never beat the "King". And I hope it stays that way forever.

Yes bitcoin has a better branding and credibility as it is the oldest and its network is the strongest. In addition bitcoin’s strong security measures and its distributed nature make it a safe and reliable choice for many users and investors. Altcoins such as shitcoins or very new projects have not yet achieved the popularity or security of bitcoin. Often the technology or plans of these altcoins are at a somewhat rudimentary level and some people are interested in buying them just for the hype or short term profit. The market value and credibility of many altcoins cannot be compared to bitcoin.

Returning to this topic, what I can add is that Bitcoin has been a bit sluggish in making new moves and innovations, despite its prominence. In contrast, Ethereum has been at the forefront of innovations like smart contracts and decentralized applications (dApps). While I can’t say it will overtake Bitcoin, if anything were to, Ethereum seems like the best candidate

If Bitcoin is considered as a popular digital currency, Ethereum is the second most popular digital currency in the crypto market, but it does not mean that Ethereum is more popular than Bitcoin and Bitcoin will surpass Ethereum in terms of popularity.  
In many cases, it is discussed that when the price of Bitcoin changes, the price of all other coins in the market changes in proportion, but we can never say that ALT coin is more popular than Bitcoin.  

Ever since Bitcoin came into the market, the popularity of Bitcoin has gradually increased. If we do an annual survey of the Bitcoin market from 2009 till now, we can see that every year the popularity of Bitcoin has increased and the value of Bitcoin has been able to record highs in a few years. There are better things ahead for Bitcoin, so I think it makes no sense to mislead people who don't know about Bitcoin that Ethereum or other coins in the market are more popular than Bitcoin.

They have to be more original and better without compromising on the ideals of True Cryptocurrency like Bitcoin in order to be a threat. Unfortunately, non so far, as far as I can tell has been able to create something original without compromising on ideals. Copying Bitcoin tech "back to back" won't make them better. The reason why Bitcoin has remain top on the list is because it is the mother of all cryptocurrencies while the children have not been able to be better than their parent without compromising on the good ideais that make the parent very valuable to people. Those who have been able to branch off from the unique family characteristics have done so in ways that weaken and expose them to issues why Bitcoin was created in the first place. They have become inferior to their parent, which is Bitcoin, and inferior things are less valuable to the superior ones.

And that is the reality and instant profit is what most of them want especially those who are still beginners who do not know and have no knowledge about crypto. And what they should know and think logically is that there is no investment that will make a profit in a short time except gambling which they should think about doing research first especially the risks that will be involved.

And there is no other coin that can make a big profit other than Bitcoin investment and I think that investment takes time to make a good profit and Bitcoin is one of them and also the best investment from other forms of investment that will make a much bigger profit if done for the long term and this is real.
