Most of the newbies still don't understand the dominance of BTC in the market or they grossly underestimate it. If they can see a lot of altcoins that are under $1, it's not a surprise that a lot of them will most likely view BTC as expensive. It's usually the faster horse that attracts them and this was even more highlighted during the massive pumps of various memecoins and NFTs. Who needs bitcoin when a token could literally fly 100x in a short time right? 
Those who look at the price of 1 BTC will always at first think that $60k is too expensive, and when you tell them that they can buy for a few tens of $, then they are very quickly disappointed with the amount they get for it. Most see this whole cryptocurrency thing as a way to get rich overnight, but all those social media stories about how someone made millions from $100 are just part of the strategy of those who invent new altcoins.
For the poll, if $2,500 is all I got to invest at this time, I'd rather split it with $2K for BTC and $500 on two low cap altcoins.
It makes sense, you can always hope that at least one of those two altcoins will pump x100 at some point - and even if that doesn't happen, you'll probably make up that $500 when the price of BTC only goes up 25%

No coin owner or a project owner can do what Satoshi did for free without aiming to be the richest man in the world. According to you, all other cryptocurrency exists because bitcoin has opened the way. But yet, not many or any wants to toe the lane of bitcoin but they are tilted towards personal enrichment.
BTC was the first, and what everyone else wanted with their projects, let everyone decide for themselves. I'm not saying that they all went in the direction of personal profit, but many projects that were created after Bitcoin have long since failed, and in 5-10 years, very likely 90% of all crypto projects that exist today will not exist or will not be relevant at all.
