I do not consider it free money. The chance for a profit, yes. The tech barrier is certainly an issue, and so is the complete understanding of mining and all of the mechanics about mining overall. From my limited understanding of mining and from what I have read, mining is still sort of the "Wild West." I must say that I do not fully understand investing either, but that does not mean I am against investing. If people feel like the understand mining and think they can make a profit, I fully support that. I wonder what the tax implications are with mining as well.
