Hello.

And this device is worth buying?

http://www.avito.ru/moskva/oborudovanie_dlya_biznesa/butterfly_labs_bitcoin_asic_miner_jalapeno_7_gha_366513560
40$ in Moscow using.

Do not buy ANYTHING from Butterfly labs or associated with it!! with that 40$ you probably won't even make 5$ worth of bitcoin! Then add electricity?= COMPLETE LOSS I have block eruptors @ 10.7 GHS and they are pretty much shut down because its not WORTH IT! and anything less than a antminer S1 200 ghs just expect to never make any kind of real money on it even the S1 isn't really profitable but its at least halfway decent but it will be just about worthlless and outdated in a month or 2 or so just like the GPU with the rising Difficulty. For mining to be profitable you need at least a ANTMINER S3 1 Terahertz these days and will cost you a couple thousand and its really not worth it your better off just buying Bitcoin it will be cheaper! The only company I would trust to buy anything off of is pretty much ANTMINER Bitmain they are the only ones who have lived up too their delivery dates.But even with them you most likely will never make enough coin to repay the investment especially when you add a power supply and cost of electricity you will make less bitcoin mining then if you took that same cash and just straight out bought it!!
What is your intentions? Do you just want to mine for a side hobby? or the fun of it and be part of the network? Or are you looking to make money? if your looking too make money? Then like I said seriously just use a solid exchange like Bitstamp or Coinbase and Buy some Bitcoin and hold and you will be ahead of the game.ALSo never use a ONLINE WALLET to store Bitcoin EDUCATE YOURSELF on how too store and Protect your BITCOIN and use something like ARMORY to store it!!!
Save yourself the time and money and headache of avoiding scams in the mining industry because you obviously don't know too much?You don't want to learn the hard way!!. If you Buy any mining equipment today?Chances are you will never make a profit and you will LOSE money with cost of machine and power supply and Electricity.Pools are struggling too find blocks also so there is no GUARANTEE on how much coin you can make even if a calculator tells you you supposedly can!and it's only going to get worse........
If you want to do it for fun and don't care about the money just want to be part of it? buy a S1 antminer from Bitmain or some USB sticks on Ebay is your best bet just make sure you Buy from a reputable vendor but understand you will never ever make a ROI RETURN OF INVESTMENT or any kind of real amount of coin for a profit and be making pennies and lucky if you break even!You will just be essentially GAMBLING and doing it for fun.
