So, if we say that 1Th/s machines now cost 5900$ plus shipping and optional customs/tax, let's say it's 6500$ in total...
If I enter into calculator that:
- average diff increase is 20%
- electricity bills are 0$
maximum profit this machine can make before new year is: 5400$
Now did I get something wrong or what?!?!
