Token price speculation (aka "crypto investing") is much more about marketing than it is about technology. This is why you see cult-like marketing attempts.
Another aspect, gambling (because most of it [trading] is gambling) can have immense distortion power over your brain. When you have money and high frequency random noise .. you're in for a nice emotional rollercoaster.
Is not pure marketing.
With BTC, you could buy in at almost any amount, get out whenever you wanted, and transfer fees were pretty low. Those aren't common traits for most other investment vehicles.
It's kind of a side effect of so much capital being locked up in a smaller and smaller percentage of the population. The folks closer to the bottom are clawing at anything that might improve their situation a little, even if it comes with a lot of risk.
Index funds/ETFs allow anyone to invest in the stock market starting with small amounts of money.
It's also amazing how small investment fees can become.
Unless they forego their employee contribution to the RSP, they have very little flexibility.
But not everyone can do a triple flip with a half twist while navigating the financial system.

It's possible to win big at negative sum games, but by definition not everyone can.
Some people got very lucky. Some people lost their life savings.
In the stock market with diversified investments, even if the market crashes, historically you would have always recovered and then some within not very many years so long as you didn't do the stupid thing and panic and sell during the crash in an attempt to time the market.
Same with Bitcoin. There is no difference between the all-time SP500 chart and the all-time BTC price chart. In both cases, historically anyone who holds long enough ("within not very many years") eventually makes money:

I'm not saying people should dump their savings into BTC, just that your argument isn't a good argument to defend the SP500. An SP500 index fund is great for other reasons, namely: it has a great track record and you can't really go wrong with investing in ~500 of the biggest American companies.
