I purchased 2 L3 miners for $1500(Each)...then after 20 days hahsnest changed the price of this device for $ 3600(That was a luck shot)...after their stock run out of L3 its price went way way way up and I sold both devices that I purchase for 7200 each ....repeating ...I purchase 2 devices for a total of $3000 and sold both for $ 14400.... some people will read this and say something like: Not true, or farming is not profitable ....I really hope that you are not one of those ..but whatever ;-p
