If you're thinking about mining Bitcoin with your own hardware, you need to understand exactly how much of an investment you're going to make and how long it will likely be before you turn a profit. Online mining calculators can help you determine if it's really worth it for you to invest in your own rig. Bitcoin is mined by networks of computers that solve difficult numeric problems to verify Bitcoin blocks of transactions. A block of transactions is made up of a reward subsidy and transaction fees. As of 2020 the block reward subsidy is 12.5 bitcoin, but the amount halves every four years with the amount scheduled to halve to 6.25 bitcoin around the 12th of May 2020. To be competitive as a miner, you will either need an ASIC (Application-Specific Integrated Circuit) unit connected to a computer or several GPUs (Graphics Processing Units) which would be better suited to mining alternative crypto currencies which could be traded for bitcoins. Go to https://www.cryptocompare.com/mining/calculator/ to get an idea of how much you would have to spend in hardware and electricity costs before you turned a profit mining Bitcoin. Keep in mind that for most individual miners, the reality is that they will spend thousands before they mine enough Bitcoin to put them over the top. If you're set on trying to mine Bitcoin despite the cost, you'll need an ASIC miner and a power supply to run it, as well as several GPUs. ASIC miners vary in price depending on their power and efficiency, but you can expect to spend between $1500 and $2000. Once you buy your hardware, you need to be able to set it up. If you don't know your way around circuit boards and computer hardware, this might not be the best hobby for you. A mining pool, such as BitMinter, CK Pool, or Slush Pool, allows you to pool your mining resources with other miners to increase your power and efficiency. Without a mining pool, you would likely mine for years before you managed to get any Bitcoin at all. When you register with a mining pool, you'll receive configuration settings you can use to add your mining rig to the pool as a worker. Your mining rig will start working as soon as you save these settings in your rig. You can control electricity costs by only running your mining rig a few hours a day. However, you're not likely to mine very much Bitcoin this way. Even in a pool, you're only going to get Bitcoin that your rig actually played a part in mining. Because mining rigs generate a lot of heat, keeping it in a basement or garage, where it may be naturally cooler, can be a good option. Not everybody has thousands of dollars to invest in a mining rig, or the tech savvy to keep it up and running that's where cloud mining comes in. Cloud mining companies own massive server farms of mining rigs and offer contracts that essentially allow you to lease the power of their miner farms for a limited period of time. There are a lot of cloud-mining scams out there. Go to https://www.cryptocompare.com/mining/#/ to research the company's reputation before you buy a contract. Smaller contracts (typically around $100) may never mine enough Bitcoin to turn a profit. Even larger contracts (several thousand dollars) may take years to mine enough Bitcoin for you to break even.

summary: Calculate mining profitability with an online mining calculator. Buy your mining hardware. Join a mining pool. Run your mining rig constantly to maximize profit. Pick a cloud mining contract package if you don't want to build your own rig.

The pain scale is used by doctors to help determine the severity of your pain. The pain scale is numbered from 0 to 10, with 0 being no pain and 10 being the most severe pain. You can rank your pain on the scale by choosing a number on the scale. The scale is as follows: 0 - No pain, feeling perfectly normal. 1 - Very mild pain. 2 - Discomforting pain that is minor. 3 - Tolerable pain that is noticeable but not overwhelming. 4 - Distressing, strong pain that you cannot adapt to. 5 - Very distressing, strong pain that gets in the way of your normal lifestyle and routine. 6 - Intense, strong pain that affects your senses and clouds your thinking. 7 - Very intense pain that dominates your senses and is debilitating. 8 - Utterly horrible pain that overrides your senses, your thinking, and your personality. 9 - Excruciating unbearable pain that require painkillers or surgery. 10 - Unimaginable, unspeakable pain that is the worst pain you have ever experienced. Based on the pain scale, your pain is considered minor if you fall within 1-3. Your pain is moderate if you fall within 4-6, and your pain is severe if you fall within 7-10. Your doctor may find it useful if you describe your pain as minor, moderate, or severe using the pain scale, as they can then more easily classify your pain as a symptom. Keep in mind that people have different levels of pain tolerance, so your idea of minor pain may be someone else's idea of moderate pain. Your doctor will take your pain tolerance into account. In most cases, the pain scale comes illustrated with cartoon faces that move from 0 to 10. The illustrated face at 0 is smiling and pain free, while the face at 10 is weeping in agony. You may be able to describe your pain best to your doctor by pointing at a certain face on the scale. The illustrated faces on the scale are often most useful for people who respond visually to pain. This can also be very helpful in a crisis situation where someone is unable to talk, or in small children who have difficulty describing their pain. The pain scale is widely used by doctors, but it is also not the only way for you to describe pain. Sometimes, it can be hard to place your pain on an exact number on the scale or within a certain range. Your "5" on the scale could be someone else's "7." Your doctor should keep the subjective tolerance of the pain scale in mind when they are using it to diagnose and treat your issue.

summary: Look at the pain scale. Identify if your pain is minor, moderate, or severe. Chose an illustrated face on the scale. Keep in mind the subjective nature of the pain scale.

Launch the Flickr website in your web browser and sign in with your username and password. Your photos are available in two different areas: Click "Camera Roll" to view all of your photos. Clicking a photo will add it to the "pile" of photos to be downloaded, shown at the bottom of the screen. To add an entire batch of photos to the download pile, click "Select All" next to the date the photos were added. If you use Flickr albums to store your photo and want to download an entire album, click "Albums," then select an album to download. Now you'll be downloading the photos you've added to the download pile. A different pop-up message will appear depending on how many photos you've selected: If you've selected one image, the message will say "Download 1 photo." Click the message box to choose where to save it on your computer. The download will begin. If you've selected multiple photos (or an entire album), the message will say "Download zip." Click the message to create a single zip file, then choose a folder to save your zip file. When the download is complete, locate the zip file. Windows users, double-click the zip file, then click "Extract" to unpack the images. Mac users can double-click the zip file to extract the images to the current folder.
