the only reason here is your choice, which aspect do you find interest in?


I think you need to be specific whenever you're making an enquiry about a particular thing, you mentioned 40k, in what currency? that aside i think regardless of the currency it might be its not enough for any start in mining and i will only advise you to start with an investment, buy bitcoin and hodl or trade if you're good at it, lastly, the more the gain the higher its capital intensive, but it will do well if you can start with buying.
