Hello,
A friend of mine told me today that he is going to build a PC from bitcoin money he made during a process called "mining". He said to me, that I should pay about 25$ on Zebrapay and after that I should start mining with Terracoin to make in 2-3 months about 1btc. My questions are: What are those programs? How can I start earning bitcoins? I am a beginner in this chapter, I only know what a bitcoin is and what it is worth. Can you explain me please how should I start?(Maybe give a link to a good, practical tutorial).
Thank you very much!
