I thank you all in advance.
Mined bitcoins are directly sent to you bitcoin address and this are the bitcoins coming from the transaction fees all around the world. It is efficient when you are doing it at large scale or by purchasing a miner so you could get nice and affordable income but doing it at small scale is not much profitable.
