And who are the scammers that you are referring to? Not all altcoins are scams, because the majority of those coins are major scams, but that does not mean that we can refer to them all as total scams.
We should still create room and study other rising projects and existing ones that provide reliable service.
It shouldn't just be all about bitcoin; bitcoin is superior, no doubt, but we should always check out others if everyone has been a maximalist on existing payment options that existed before Bitcon who could have discovered the features of bitcoin.
"Meme" coins are usually a "gold mine" for scammers. The majority are them are just pure cash grabs. Legitimate projects are those who bring real use cases to the world. They provide innovation compared to the rest of the pack. Bitcoin is the most "trusted" cryptocurrency because it's the one project that started it all. But that doesn't mean it's free from scams. Scammers can use the cryptocurrency to fool others for their own benefit.
I understand why maximalists prefer BTC above anything else. It's because there's no other project that is as decentralized and censorship-resistant as BTC. But I'd say, buying and holding a few prominent alts alongside BTC never hurts. Just as long as you avoid investing more than what you can't afford to lose. It's a "free" market (as in liberty). So people decide whenever to support BTC or alts (or a combination of both) based on their needs. I'd expect Bitcoin to withstand the test of time as long as it stays true to its principles of decentralization.
