It is a way to store your bitcoins. Specifically, it is software that has been designed to store bitcoin. It can be run on your desktop computer, laptop, mobile device (except, as yet, Apple) and can also be made to store bitcoins on things like thumb drives. If you are concerned about Bitcoin Forum bitcoin-forum-btc.6/, then that is a good option. Even the Winklevoss* twins, who have millions invested in bitcoin, put their investment on hard drives which they then put into a safety deposit box.
*The Winklevoss twins are the ones who originally had the idea for a social networking site that became Facebook. They hired Mark Zuckerberg who took their idea as his own and became immensely rich.
What do you need to know about having a bitcoin wallet on your computer?
Below you can download the original bitcoin wallet, or client, in Windows or Mac format. These are not just wallets, but are in fact part of the bitcoin network. They will receive, store, and send your bitcoins. You can create one or more addresses with a click (an address is a number that looks like this: 1LyFcQatbg4BvT9gGTz6VdqqHKpPn5QBuk). You will see a field where you can copy and paste a number like this from a person you want to send money to and off it will go directly into that person’s wallet. You can even create a QR code which will let someone take a picture with an app on their phone and send you some bitcoin. It is perfectly safe to give these out – the address and QR code are both for my donations page. Feel free to donate!
NOTE: This type of wallet acts both as a wallet for you and as part of the bitcoin system. The reason bitcoin works is that every transaction is broadcast and recorded as a number across the entire system (meaning that every transaction is confirmed and made irreversible by the network itself). Any computer with the right software can be part of that system, checking and supporting the network. This wallet serves as your personal wallet and also as a support for that system. Therefore, be aware that it will take up 8-9 gigabytes of your computer’s memory. After you install the wallet, it will take as much as a day for the wallet to sync with the network. This is normal, does not harm your computer, and makes the system as a whole more secure, so it’s a good idea.
