The very first line of the article relates gambling as an "ancient activity of entertainment".That describes it all,people do it for ROI's and what not.Its like the primary source of income for a lot of bitcoiners.The article doesn't explain anything new but the same old stuff what we all know.
Hey here's what most valuable suggestion they have chosen to enlighten people.
What is the point of this article again if I'm reading it to come up with a strategy myself ?
You got the point. The title says: "How can Bitcoin Gambling be Profitable?", but there isn't any tip to make it profitable... It's just an article, maybe to make people sign up on that MMORPG Dragon's Tale or any other casino with site owner ref link.
No problem if OP wants to advertise his site and his links, but it's a deceptive article.
