For me too, this basically is the reason, its the digital age and the entire concept behind cryptocurrency (digital money) appeals to this digital age and young people who have been empowered by the internet.
Also formerly when we hear of investments, it always pointed towards buying stocks and shares from companies, real estate, gold and all that, they are all nice, but sometimes require a very huge capital to start, plus the wait period is also an issue to get good ROI on investment. Right now with cryptocurrency which is easy to understand by young investors, theres an opportunity for investment with very promising ROI, so a lot of young investors will definitely prefer it.
