Bitcoin Wallet: Keep Bitcoins safe

A Bitcoin Wallet keeps the private keys each user needs to access a bitcoin address and receive and send credit. There are several ways to store bitcoins securely while maintaining an address. The following options, which we will discuss further in the following article, are available to the user:

Destop Wallet (local)
Mobile Wallet (App based)
Online Wallet (online)
Hardware Wallet (on the stick)
Paper Wallet (Black on White on Paper)
To keep Bitcoins secure, you can even use paper wallets all over the world. Of course, it is important and advisable to secure its bitcoin wallet adequately.

Bitcoins are a highly modern equivalent to cash, and almost every day more and more companies accept the digital currency as a means of payment. You may know how bitcoins are generated and how a transaction works, but how are bitcoins kept? Fiat money can usually be stored in a physical Wallet, and so it works similarly with Bitcoins - only digital.

Strictly speaking, technically speaking, one does not really keep bitcoins, but rather the digital keys (keys) to access a public Bitcoin address and authorize a transaction. This information is stored in a Bitcoin wallet. Bitcoin wallets can be divided into 5 different categories: Desktop Wallet, Mobile Wallet, Paper Wallet and Hardware Wallet. Here we describe how they work in detail.

Desktop Wallet

If you have already installed an original bitcoin core (Walcoin Core Wallet), you are already using a wallet without knowing it. In addition to forwarding transactions in the network, you can use the software to generate a bitcoin address to receive or send Bitcoin credit and keep the associated keys.

There are also other desktop wallets, all of which offer different features. MultiBit runs on Windows, Mac OSX and Linux. Hive is an OS X based wallet with a few unique features including an app store with access to various Bitcoin services.

Some desktop wallets are aimed only at security: Armory, e.g. In exactly this category.

Other wallets, in turn, were based on anonymity, e.g. DarkWallet. This wallet is a browser plugin, which uses a "Coin-Mixer" to exchange the user's credit among each other, thus making the tracking more difficult and obscuring the identity.

Mobile Wallet

Desktop Wallets are as far as nice and good but very impractical when it comes to various shops or on the road with Bitcoin to pay. Here the mobile wallets can trump. The mobile wallets are installed as an app on the smartphone and store the private keys directly on the mobile device. Thus, with the mobile phone Bitcoins can be received and shipped, and in seconds.

Some mobile Bitcoin wallets even support Near Field Communication Technology (NFC). In this case, the smartphone must only be held at the terminal without scanning a QR code or entering a Bitcoin address.

One property, however, shares all mobile wallets: they are not full-fledged Bitcoin clients, because they would have to download the ever-growing and now several Gigabyte large blockchain. This would probably break the credit of many hand-users and is therefore not marketable. Therefore, almost all mobile wallets use the "Simplified Payment Verification" (SPV), which downloads only a small part of the blockchain and is completely sufficient for a secure transaction.

Android and iOS Wallets include: Jaxx (Bitcoin & Ether), Bread Wallet (Bitcoin), Bitcoin Wallet, Mycelium, Xapo and Blockchain. They keep the keys encrypted on the mobile phone and also create a web-based security scanner.

Apple first paranoid against bitcoin-Wallets and banished first in November 2013 the Coinbase Wallet from the App-Store and then in February 2014 the Blockchain App. In July 2014, however, the apps were resumed and since then almost all well-known Wallet vendors have been found in the Apple Store.
