How to Store Your Bitcoins - What are the type of bitcoin wallets
What are the type of bitcoin wallets :
Bitcoin wallets store the private keys that you need to access a
bitcoin address and spend your funds. They come in different forms,
designed for different types of device.
You can even use paper storage
to avoid having them on a computer at all. Of course, it is very
important to secure and back up your bitcoin wallet.
Bitcoins are a modern equivalent of cash and, every day, another merchant starts accepting them as payment. We know how they are generated and how a bitcoin transaction works,
but how are they stored? We store fiat cash in a physical wallet, and
bitcoin works in a similar way, except it's normally digital.
Well, to be absolutely accurate, you don't technically store
bitcoins anywhere. What you store are the secure digital keys used to
access your public bitcoin addresses and sign transactions. This
information is stored in a bitcoin wallet. Bitcoin wallets
come in a variety of forms. There are five main types of wallet:
desktop, mobile, web, paper and hardware. Here’s how they work.
Desktop wallets
If you have already installed the original bitcoin client (Bitcoin Core),
then you are running a wallet, but may not even know it. In addition to
relaying transactions on the network, this software also enables you to
create a bitcoin address for sending and receiving the virtual
currency, and to store the private key for it.
There are other desktop wallets too, all with different features. MultiBit runs on Windows, Mac OSX, and Linux. Hive is an OS X-based wallet with some unique features, including an app store that connects directly to bitcoin services.
Some desktop wallets are tailored for enhanced security: Armory falls into this category. Others focus on anonymity: DarkWallet
– uses a lightweight browser plug-in to provide services including coin
‘mixing’ in which users’ coins are exchanged for others’, to prevent
people tracking them.
Mobile wallets :
Desktop-based wallets are all very well, but they aren't very useful
if you are out on the street, trying to pay for something in a physical
store. This is where a mobile wallet
comes in handy.
Running as an app on your smartphone, the wallet can
store the private keys for your bitcoin addresses, and enable you to pay
for things directly with your phone.
In some cases, a bitcoin wallet will even take advantage of a
smartphone’s near-field communication (NFC) feature, enabling you to tap
the phone against a reader and pay with bitcoins without having to
enter any information at all.
One common feature of mobile wallets is that they are not full
bitcoin clients. A full bitcoin client has to download the entire
bitcoin blockchain, which is always growing and is multiple gigabytes in
size. That could get you into a heap of trouble with your mobile
service provider, who will be only too happy to send you a hefty bill
for downloading it over a cellular link. Many phones wouldn't be able to
hold the blockchain in their memory, in any case.
Instead, these mobile clients are often designed with simplified
payment verification (SPV) in mind. They download a very small subset of
the blockchain, and rely on other, trusted nodes in the bitcoin network
to ensure that they have the right information. Examples of mobile wallets include the Android-based Bitcoin wallet, Mycelium, Xapo and Blockchain (which keeps your bitcoin keys encrypted on your phone, and backed up on a web-based server).
Apple is notoriously paranoid about bitcoin wallets. Coinbase had its mobile wallet app pulled from the app store altogether in November 2013, and this was followed in February 2014 by removal of Blockchain’s iOS app. However, in July 2014, bitcoin wallet apps began to reappear on the iOS store, and now all of the major bitcoin wallet providers have released new editions of their previous apps. The Aegis Bitcoin Wallet even supports android smartwatches
There are also other types of wallets that can be used on a mobile, such as the browser-based wallet
Web-based wallets store your private keys online, on a computer
controlled by someone else and connected to the Internet. Several such
online services are available, and some of them link to mobile and
desktop wallets, replicating your addresses between different devices
that you own.
One advantage of web-based wallets is that you can access them from
anywhere, regardless of which device you are using.
However, they also
have one major disadvantage: unless implemented correctly, they can put
the organisation running the website in charge of your private keys –
essentially taking your bitcoins out of your control. That’s a scary
thought, especially if you begin to accrue lots of bitcoins.
Coinbase,
an integrated wallet/bitcoin exchange operates its online wallet
worldwide. Users in the US and Europe can buy bitcoin through its
exchange services.
Circle offers
users worldwide the chance to store, send, receive and buy bitcoins.
Currently only US citizens are able to link bank accounts to deposit
funds, but credit and debit cards are also an option for users in other
countries.
Blockchain also hosts a popular web-based wallet, and Strongcoin
offers what it calls a hybrid wallet, which lets you encrypt your
private address keys before sending them to its servers – encryption is
carried out in the browser.
Xapo aims to provide the convenience of an simple bitcoin wallet with the added security of a cold-storage vault.
Hardware wallets
Hardware wallets are currently very limited in number. These are
dedicated devices that can hold private keys electronically and
facilitate payments.
Trezor hardware wallet
The Trezor hardware wallet is available from $99 directly from SatoshiLabs
The Trezor hardware wallet
is targeted at bitcoiners who wish to maintain a substantial stash of
coins, but do not want to rely on third-party bitcoin storage services
or impractical forms of cold storage. Read our Trezor hardware wallet review to find out more.
Ledger USB wallet
The Ledger Wallet Nano is Available driect for €34.80 and also from Overstock
The compact Ledger USB Bitcoin Wallet uses smartcard security and is available for a reasonable price. CoinDesk reviewed this wallet in December 2014.
KeepKey launched a hardware wallet in September 2015, which is priced at $239 a unit. The KeepKey wallet software was originally a fork of Trezor's code.
The KeepKey hardware wallet is for sale for $239.Mycelium, Cryptolabs and BitStash currently
have a hardware wallets in development, but, as of September 2015
none of these had delivered finished products. Announced on February 4th
2014, is the Nymi sports wristband from Boinym, which can act as a bitcoin wallet and uses your heart rhythm as a security key.
