It's really a tough investment doing mining since there are so many things that you need to consider before starting mining.

You don't actually know if your going to earn a good amount of profit or is it really worth it doing mining, you need to consider some things like your country if you are in a tropical country I thing it is not recommended to start mining since the hardware is going to produce a lot of heat, and getting overheat is one of the causes of the hardware to easily break. Also now that even small miners cannot earn a profit because of the bitcoin halving.
