There have been many discussions in the past few years about why people are into crypto. Some are in it for the quick gains, others because they hate the current financial system, others because they are bored and might as well put all that spare time to good use. It's like all the dudes that live in the friend zone of a hot chick, some say she is funny, others that she has a nice personality. Of course all these arguments might be valid to some extent but they don't offer the full picture.
Both in the hot chick analogy and in the crypto world, all the peeps have something in common: the prospect of rewards. Usually people are after the monetary kind of rewards, but not always :P
