I am looking to buy a bitcoin miner for a cheap price. I was really looking into a butterfly labs 10GH/s for $250 Link(https://products.butterflylabs.com/homepage-new-products/10-gh-s-bitcoin-miner.html) Is it worth it? I know a decent amount of information about bitcoins and such, but I dont have a big budget here. Only about $600 Max. What should I get or should I get one? If I get one I will be joining a pool. But how much bitcoin(s) can I make which a certain amount of GH/S? Thanks and I wish many bitcoins to you!! Feel free to respond and give me advice.
