Newbies gamble, but they'll learn the hard way like ME. Haha!
Plus I believe it's part of "The evolution of a Bitcoiner". They come to "get rich quick", then learn more about the basics of the protocol, learn different concepts/theories/debates, THEN stay for the revolution.
Haha, I haven't learnt my lesson in all my time gambling. Every time I think "Ooo, I've gotten smarter and more disciplined about this thing, good for me!" I go and do something random and stupid and blow something on a session. But hey, we gotta pay for fun!
P.S. I actually came to Bitcoin because I had nothing to do for weeks in bed. And then actually used it when I wondered if it could help solve a really frustrating money problem (it did!). Now I did get into an ICO or two with the "get rich quick" hope in 2017. Sue me, I'm a gambler =D
