Hello everyone.
So I always new about Bitcoin and Bitcoin mining but never really looked into it in great detail. My friend and I are thinking of starting a miner and have £200 starting money. If any of you guys could be useful and recommend us anything it would be appreciated.
What miner do you recommend? Also I don't understand fully about the psu is it necessary or what?
Also whatever miner you recommend what profit do you think we could get, assume the electricity costs are free.
Any additional information that you can add for us.

Thankss.
