Now, if you're really worried about security, first thing I'd fix is instant messaging and e-mails. Non of those are encrypted by default. Meaning whatever messages you send to your friend or whoever else by e-mail or instant messaging, a middle guy can pick it up and read it. It's called a middle-man attack... This is a completely different topic and I won't get into that now. At current moment people can't break messenger protocols, but they can still read what your're sending to people.

As far as Diversification goes, strategy seems to be producing differenct picks every session. Currently picks are predominately USD, but other currencies are starting to break-out. You can download my digot picker version 1.0 from http://www.freewebs.com/xcash. This is only digot picker that uses this strategy. I'm working on version 2.0 that will allow several different strategies. The digot picker will make you less dependent on other sites that offer digot data. You can download your own data directly from DX as early as 15 minutes after session with my digot picker. You will also be assured that data is correct. I've seen mistakes on some of other sites offering digot data. Take charge, don't wait for your data, do it yourself with digot picker 1.0.
