They are many reason but likely to start with major one; is to make profit because crypto is one of the most viable investment now I.e very lucrative and convinient, to be in vogue because is another of investing after forex but saver than forex, because that is where the world is going very soon I.e as a medium of exchange and many more
I have many reasons also why I join crypto, personally i want to become financially stable and independent. Where i can stand with my own feet without asking from my parents. Make use of my free time in more important things than spending it to some useless things. Earning big profit and save money to build my own business in the near future.
