Everything pooya87 said was completely correct.
I just wanted to add a couple of things:
- you speak about a farm. Luckily you also realise it's nothing you can do in a flat. Even if you find a place where you can place miners, you have to know that mining nowadays is pretty hard. It's defenatly not free money, if you don't know what you're doing you won't be able to recuperate your investment in ASIC miners (it has much to do with the price, import taxes, electricity rate, market fluctuations,...)
- when chosing a wallet, please chose a safe one: a paper wallet or hardware wallet or at least a desktop wallet. Please stay away from online ones
- share your plan on this forum BEFORE executing it! To many people just think they have a plan, execute it, and when it goes wrong: come to this forum. At this point, it's usually to late for us to give good advice, and you'll lose a lot of money
I just wanted to say these things for a second time:
- bitcoin is volatile. It's a risky investment. You might gain (a lot of) FIAT, but you can also LOSE your money!!!
