5700XT here cost around 550 euro, lets say 600 (735$) for the sake of it. Im willing to invest around 11k euro into the whole mining rig, thats a little over 13.400 dollars, the electricity here is 0.15 e/kw (0.18 $/kw), but there is a chance to get a plan for huge electricity consumers, 6 euros (7.3 $) per month for unlimited electricity.
My question is, can something proper be achieved with those kind of insights and if so, wont my rig be obsolete after eth 2.0 finally drops?
