I heard mining bitcoin is very expensive and you need a very big amount money to buy the equipment also known as mining rig. I have a friend a that try that mining rig he said to me that he waste a lot of money because the consumption of electricity is very expensive and also the maintenance.
The electricity consumption is the biggest problem we have when we want to do mining in our place. Second problem is the very expensive mining rig. We can not afford the equipment and also not good knowledge about how to operate the mining. For me i dont like mining.
