The most important information for a beginner is:
Don't start to mine if you want to make a profit!Mining nowadays is impossible with general-purpose hardware (CPU & GPU).
Special-purpose bitcoin hardware is pretty expensive and can only yield a profit if
- you get it quickly enough after it starts being available (because on one hand, difficulty adjusts to adapt to total mining power, which is normally increasing, and in addition, newer miners have better hash performance per consumed energy)
- your electricity is cheap enough (otherwise mining rewards will not be enough to pay for the miner operation)
- you get the miner cheap enough so that at one point your mining rewards minus operating costs exceed investment costs
As a beginner, you are very unlikely to meet all three requirements, so the chances are high that your mining business will be lossy.

By the way, your signature advertises a "service" that claims to yield 100% monthly profit for bitcoin investments. This is impossible to achieve, that service is with absolute certainty a scam. Well maybe it works if you happen to find "BITCION" to invest...
