Wrap your device in plastic wrap, or place it in a plastic bag. This will put a barrier between the device and the conductive aluminum layer. It can also serve as a waterproof layer for extra protection. You can wrap the item in cloth to help prevent edges from poking holes in the plastic and/or aluminum layers, though this is not necessary. The metal allows radiation to travel along its surface but not through it. You should cover every inch of the device in at least three layers of aluminum. Protection can be maximized by adding plastic layers in between each layer of aluminum foil. This will create alternating layers of conductive and nonconductive materials and shield your device from harmful electromagnetic radiation. A Faraday cage is designed to protect devices from an EMP (electromagnetic pulse) blast. This is a high intensity blast of radiation that comes from a weapon or a naturally powerful source (e.g. the sun). You can also use a Faraday cage to block a cell phone or radio from getting reception, or prevent your expensive car from being stolen by protecting its (keyless entry) keyfob. In this case, you would need fewer layers since the radiation is much weaker than an EMP blast. Adding adhesives like glue between each layer will make your faraday cage more sturdy and permanent, but it will be harder to remove.

Today, buying and selling Bitcoin is easier for beginners than ever. As your first step, you'll want to sign up for something called a Bitcoin wallet. Like its name suggests, your wallet is a digital account that makes it fairly easy and convenient to buy, store, and sell your Bitcoin think of it like a universal Bitcoin checking account. Unlike a checking account, however, starting a Bitcoin wallet usually takes less than a minute, can be done online, and is quite easy. Sites like Coinbase.com, Coinmkt.com, Blockchain.info and Hivewallet.com are are just a few examples of reputable, reliable and user-friendly sites for beginners to create their first wallet. Once you have a wallet, it's time to fill it with Bitcoin. Typically, to do this, you'll need to supply the financial details for a real-world bank account just like you would if you were setting up a PayPal account or signing up for another online payment service. Usually, you'll need at least your bank account number, the routing number for the account, and your full name as it appears on the account. You can almost always find these on your online banking account or on your paper checks. Note that you may also be asked to provide contact information, like a phone number. To be clear, linking your bank account to your Bitcoin wallet is not any more of a risk to your personal security than it is to shop online. Virtually all reputable Bitcoin services make a point to advertise their high standards for security and encryption. While Bitcoin services have been targeted by hackers in the past, so too have many major online retailers. Once you've supplied your bank information and it's been verified by the Bitcoin service, it should be fairly easy to start purchasing BTC and adding it to your wallet. Usually, on your wallet page, there should be an option labeled "Buy Bitcoin" or something similar clicking this should take you through a straightforward transaction process that uses money from your bank account to purchase BTC. Note that the price of Bitcoin can (and does) change from day to day sometimes significantly. Because Bitcoin is a relatively new form of currency, its market has yet to become stable. The current dollar-to-BTC exchange rate should be clearly listed when you buy it as of October 2014, 1 BTC was equal to about $350. In recent years, an increasing number of businesses have begun to accept Bitcoin as a valid form of payment. Though these businesses still represent a minority, some major names have already made the transition. Below is just a short list of online vendors that accept BTC: Amazon Wordpress Overstock.com Bitcoin.travel Victoria's Secret Subway Zappos Whole Foods If you're market-savvy (or lucky), you can conceivably generate value for yourself this way by buying Bitcoin when its price is low, then purchasing goods when the value of Bitcoin is high to get a favorable deal on the goods. You can then sell these goods to make a profit or simply keep them. Unfortunately, selling Bitcoin isn't quite as easy as buying it. There is no easy way to "cash out" your Bitcoins and receive money in your bank account instead, you'll have to find a buyer who's willing to pay for them with money (or good/services). In general, one of the easiest ways to do this is to sign up with an online Bitcoin marketplace. Once you find a buyer, you will complete the transaction through the website but will otherwise deal directly with him or her. To use this method, you'll usually have to register a seller account and verify your identity in a process separate from the one used to create your wallet. In the US, CoinCola, CoinBase and LocalBitcoins are three websites that offer this sort of selling service. In the UK, BitBargain and Bittylicious are two reputable options. In addition, some sites like Purse.io allow sellers to give Bitcoin to buyers who then use their own money to purchase goods online and send them to the seller in essence, this is a roundabout way of using Bitcoin to buy from vendors that do not accept the currency. Another option for sellers is to use a Bitcoin exchange. These sites work by pairing sellers with prospective buyers. Once a seller is found, the website acts as a sort of intermediary or escrow service, holding the money until both parties are verified and the transaction is completed. Usually, there is a minor fee associated with this service. Selling with this method is not usually an instantaneous process. In some cases, users have even complained that exchange services can take an inordinate amount of time to complete transactions compared to other options. Reputable, well-known exchanges include Circle, Kraken, and Virtex. In addition, some exchange sites like Binance, Bittrex, Bitfinex and Bitcoinshop allow you to trade Bitcoin for other digital currencies (like Dogecoin, Ethereum, Litecoin and Monero).
