Besides trying to get rich quick, what are the main avenues the average person gets introduced into crypto these days?

I originally learnt and got introduced to crypto back in 2012-14ish (can't remember exactly, Bitcoin was worth $70 when I first purchased) due to learning about dark markets (e.g. original silk road) and being intrigued but what was out there.

I ended up purchasing a few things out of interest and trying to figure it all out.

It seemed back then this was the main reason people flocked to crypto, but now with the smorgasbord of coins and different aims and markets is there still some stand out reasons people get into it (besides the obvious)?
