what is the difficulty exactl..for example its currently at 19.3 million...what does this mean.
how can i tell how much of a bitcoin i have personnaly mined. i can see my btc accepted but where does that translate in bitcoins?
also should i have more than 1 worker...what difference does this make?
thanks for any help?
You purchased a miner without understanding what 'difficulty' is? Sigh. Reading through some of the wiki articles would be a start:
https://en.bitcoin.it/wiki/MiningBasically difficulty and earnings are inversely proportional. Difficulty is directly related to how quickly blocks are found. If difficulty doubles, your earnings are cut in half. At any given point in time, the current difficulty represents what is required for the entire bitcoin network to mine approximately 1 block every 10 minutes. As more miners join the network, blocks are found more quickly and that causes difficulty to go up to compensate.
At the beginning of 2013, difficulty was 3 million. Now it is 20 million. Some believe that by the end of the year it will be 200 million (at which point, of course, your miner will be earning 1/10th of what it is now).
To see how much you have personally mined, log in to the bitminter website, click on the My Account button, and you will see a table with numbers: Balance (how much of your earnings are available for withdrawal), Unconfirmed (how much you have 'in the queue', that hasn't yet confirmed), Future (the sum of the previous two), and Expected Per Block (how much you will earn if the pool finds a block). When the pool finds a block, you get a portion of the earnings which shows up under your 'Unconfirmed' column. However, before you can withdraw it, you need to wait 120 blocks (around 20 hours) for it to confirm.
Whether you have 1 worker or multiple doesn't matter. Some people like to manage their physical GPUs/FPGAs/ASICs/PCs separately so they assign each with its own worker. Others just use a single worker. There is no particular advantage to either.
