Is cheap bitcoin mining still possible? Hi I am kind of new to bitcoin mining and I am on a budget. Is it still possible to profit from the low price range miners? I have a budget of $250 and I will be using a raspberry pi 3 to control how ever many I buy. I can afford usb mining erupters and power outlets but I just need to know if I can buy anything that could be profitable. And my friend might help me out with $150 so maybe take that into consideration? But any help would be nice! Thanks!
