Hello everybody,

I am a new user, but I have collected some informations about the bitcoin and the mining.
First of all I would like to start mining using some savings I have.
All advices will be taken into account.
I would like to start with 3 terahash and especially using the devices from this site https://products.butterflylabs.com/
So I would like to know what is needed. Do I need to buy the asic and need a case where to install it? I saw the imperial monarch can be plugged via usb. is it true? and it's also quite powerful, I think. 1 TH/s is pretty good, don't you think?
Second, I have read that more or less the difficulty increases every two weeks with an approximate rate of +30%. So if I have 3 TH/s, the electric power costs me about 0,06 and I need an initial investment of about 6000 for the asic what would by my ROI and more particularly how much time would I need to wait with those assumptions? (let's also say that the bitcoin is kept at 440 euros all the time as a costant). And what about 4 TH/s with an invstment of 8000 ?
I forgot to mention the power. 1 TH/s needs 650 watt. (price for electric power again is 0,06 ).

Thank you very much.

P.S. Not interested in comments like "don't do it" and it's impossible to say since I said to keep constant the value of the bitcoin and that the rise in difficulty would be about 30% every 2 weeks.

I won't tell you not to do it, but, I will tell you to stay away from BFL. Look at all of the threads out there about the woes people are suffering with that company.
