Or is it serious that money should be earned through hard work?

Well I think people forget that in order to earn money to even invest in cyrpto, you have to work, and often work hard! You also have to have the discipline not only to save more than you earn, but you also have to spend time researching these different currencies and making an informed decision about which one to purchase.

Even if you're just looking to ride the way of price increases and you throw money at the most popular coins, you still have made yourself informed and still had to save money!
