Before I start saying bad facts about BFL Butterfly Lab, I just want to say that I ordered mining equipment from BFL before and have received it, but I must it took a long time, a year or so. Indeed terrible, the good news is they do deliver but just takes hec long time.
As a result of Butterfly Lab BFL slow in delivery, a lot of people are upset because the value of Bitcoin dropped, while the difficulty mining level also increased. If people to get mining equipment today, they will not be able to make the same amount of Bitcoin as they would if they just buy Bitcoin with cash.
Some people are mining Bitcoin for now a day. For those that have a small operation farm in the garage or where ever in the house, you know you’re suffering, even if you get the equipment for free but electricity cost will kills you.
