Maybe one could, but why would it? If it did, wouldn't it get replaced? If it will get replaced too why value it in the first place?
Most altcoins are hobbled by their creators motivations to line their pockets. E.g. Ethereum premined 72 million tokens.
Most altcoins that don't have extremely scammy origins you hardly hear about because they don't have fat pocket books to buy placement on exchanges/website listings/conferences.
To differentiate themselves from Bitcoin altcoins make various design departures, some might be useful-- but if they're really that useful, Bitcoin will likely adopt them, so they need design departures that Bitcoin would never adopt and those tend to be ones that make the economics suck or which severely hobble decentralization at least in the long run.
That's certainly true, mate. Most altcoins are simply created to benefit the developers instead of the end user. It's no wonder why they've failed in taking Bitcoin place across the crypto market. Not to mention, most altcoins have a lesser degree of security than Bitcoin. Many people trust the pioneer cryptocurrency because it's extremely secure, and serves well as a store of value. If altcoins want to be as good as Bitcoin, they need to have extremely active development, innovation, and most of all, marketing/promotion. This is the key towards achieving mainstream adoption as we know it. Only then, altcoins will be able to present themselves as true contenders of Bitcoin.
Still though, Bitcoin is the father of Blockchain technology. Considering that every cryptocurrency uses Blockchain as their base layer, it's very unlikely that they'll replace the original project anytime soon. Also, the most prominent altcoins on the market today, can easily be replaced by newcomers in the crypto space. In the world of crypto, nothing is certain. Even Ethereum could easily lose its place on the market in the long run. But Bitcoin will remain as the top cryptocurrency of the market for the foreseeable future. Hence, it's impossible to replace Bitcoin anytime soon. Just my thoughts
