I would think collaborating or investing with big companies already actively mining would be a better option because of the expenses involved in mining especially bitcoin.I'm curious about something. Lets say I wanted to be making like $1000 in bitcoin for the month, at least. How many PCs would I need to be able to mine that amount in a month alone? How much for $5000 a month or even more? If I can build a setup where I can draw a lot of money, I would love to give it a try. But how much do you think it'd cost to set up?
