Ok, you found one that was corrected. The point remains that Bitcoin facilitates loss in a way that no other payment system does and has no insurance or fraud protection covering it. I was one of the lucky ones that made money when you could mine with a gpu at almost no cost other than electricity. From now on, people will need to put their own money in to it and they will only make money if they live long enough to see an enormous increase in the exchange rate. It's a gamble that may pay off but it's high risk.

There are many secure investments that pay 10-20% a year. If you start today with $10,000 and average 20% a year for 20 years, you'll have over $380,000. Add $2,000 a year to the pot, and you'll wind up with $756,751 after 20 years. Granted, 20% a year is not super easy to achieve. But even if you only make 10% a year, you're still going to become very wealthy over the long term. People are getting scammed or throwing their money at gambling bitcoins because the return isn't happening fast enough for them. They should simply try a stable long term investment.
