I think the cost for fuel should bre reduced from $800 to $400. Because as it stands, players with no money can't make a profit off of bitcoin mining because the cost of the fuel (3,200 to completely fill the generator)
greatly outweighs the money you make from low value miners. Now i know bitcoin miners are supposed to only be good when you have a full server rack, but still. People don't buy them even though they are legal because they cant make good money unless they invest the $300,000 they don't have. I myself have 1.4 mil but i feel that they are kind of useless to new players.
