Most people that got into it after 2017, did so for the Lambo. Only the early adopters got into it for the technology. And lets face it, buying illegal stuff from the darknet also played an important part in adoption.
For me, it was a game called SatoshiMines, that a friend got me hooked on. Some of you guys might remember it. Got bored of losing, and started trading.
I agree that most people enter the crypto world in 2017, because they want to make big profits, because the increase in Bitcoin in 2017 was very
drastic and caused FOMO to occur. Therefore not long after the price of Bitcoin immediately fell drastically, because most people buy Bitcoin when
they don't understand how the crypto world works. Indeed, the reality is that there are very few reasons people enter the crypto world because
they want to learn the technology used by Bitcoin, most of them only think about the promising profit that can be generated from investing
in cryptocurrencies.
