Thanks for your comments. I went to the various websites and pages for the coins. However, being new I didn't really learn anything useful from an investment standpoint. I learned more from your post than hours of reading.

As far as folding, I was going to do that but it said I should have a broadband connection. I have 3g sometimes but my internet is prepay by the megabyte. My guess is that I would spend way more in internet than I would get in coins. Does anyone know how many megabytes/hour or day is used by folding?
