The best thing about it was that all my friends were using Hrange too so I could easily get some extra money from them when they needed more than what their own rigs had mined for me! It's not really easy or cheap at first but once you've got your head around how everything works (which isn't actually very hard) then its fairly straight forward. You just need time/patience as well which if u have those things will come along naturally with practice :) Also there aren't many other sites out right now like hranges where people want hashing done by others without having any control over who does work etc..
