This blog posts on a wide variety of bitcoin-related topics.  Mostly about ways to earn bitcoins that do not rely on effort or work such as paid-to-click, paid-to-view, or other such methods that require someone to spend hours to earn very little.

The latest post is about a site offering cloud-mining services at extremely reasonable rates.

The perks of the site are (as seen on the blog):

- A mining calculator to determine what your monthly revenue will be, based on the hashing rate you enter.
- Buy and sell GH/s instantly, 24/7
- Run a miner on your PC and mine the GHash.io mining pool to increase your CEX.io profits.
- Extremely user-friendly interface.

Information DIRECTLY from their site:

- No shipping delay.
- All GHS are delivered instantly and begin mining!
- No breakage or power loss.
- The GHS are safely stored in the data-centre with proper maintenance.
- No excessive electricity costs or cooling issues.
- Everything is handled by our affiliates’ maintenance staff for a small fee
