WHAT IS BITCOIN?
Bitcoin is an innovative payment network and a new kind of money. Bitcoin uses peer-to-peer technology to operate with no central authority or banks managing transactions and the issuing of bitcoins is carried out collectively by the network. Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and everyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system.

Bitcoin Wallet.
A Bitcoin wallet is a software program where Bitcoins are stored. To be technically accurate, Bitcoins are not stored anywhere; there is a private key (secret number) for every Bitcoin address that is saved in the Bitcoin wallet of the person who owns the balance. Bitcoin wallets facilitate sending and receiving Bitcoins and gives ownership of the Bitcoin balance to the user. The Bitcoin wallet comes in many forms; desktop, mobile, web, and hardware are the four main types of wallets.
Breaking Down Bitcoin Wallet.
A Bitcoin wallet is also referred to as a digital Wallet. Establishing such a wallet is an important step in the process of obtaining Bitcoins. Just as Bitcoins are the digital equivalent of cash, a Bitcoin wallet is analogous to a physical wallet. But instead of storing Bitcoins literally, what is stored is a lot of relevant information like the secure private key used to access Bitcoin addresses and carry out transactions. The four main types of wallet are desktop, mobile, web, and hardware.
Desktop wallets are installed on a desktop computer and provide the user with complete control over the wallet. Desktop wallets enable the user to create a Bitcoin address for sending and receiving the Bitcoins. They also allow the user to store a private key. A few known desktop wallets are Bitcoin Core, MultiBit, Armory, Hive OS X, Electrum, etc.
Mobile wallets overcome the handicap of desktop wallets, as the latter are fixed in one place. These take the form of paid apps on youOnce you run the app on your smartphone, the wallet can carry out the same functions as a desktop wallet, and help you pay directly from your mobile from anywhere. Thus a mobile wallet facilitates in making payments in physical stores by using "touch-to-pay" via NFC scanning a QR code. Bitcoin Wallet, Hive Android, and Mycelium Bitcoin Wallet are few of the mobile wallets. Bitcoin wallets do not generally work on both iOS and Android systems. It's advisable to research your preferred mobile Bitcoin wallet as several malware softwares posing as Bitcoin wallets are an issue.
As for web wallets, they allow you to use Bitcoins from anywhere, on any browser or mobile. The selection of your web wallet must be done carefully since it stores your private keys online. Coinbase and Blockchain are popular web wallet providers.
Hardware wallets are by far the most secure kind of Bitcoin wallet, as they store Bitcoins on a physical piece of equipment, generally plugged into a computer via a USB port. They are all but immune to virus attacks, and very few instances of Bitcoin theft have been reported. These devices are the only Bitcoin wallets which aren't free, and they often cost $100 to $200.

The 7 Best Bitcoin Wallets of 2019.
Protect your investments.

Bitcoin has taken the world by storm, offering a currency alternative to the government-backed currencies we all know from daily use. Proponents argue that the digital currencies are easier, safer, and offer better privacy than traditional currencies. Because the value of a Bitcoin compared to the U.S. dollar and other currencies has skyrocketed over the years, it has shown up on some people's radar as an investment opportunity as well.
Before you put a dollar into Bitcoin or any other cryptocurrency, it is important to understand the risks. Bitcoin could easily double in value over the next few years, but it could just as easily drop to near zero in value. Only put in what you can afford to lose because there is a chance you won't get it back. If you understand the risks and you're ready to move forward, any of these best Bitcoin wallets should have you covered.
Coinbase is one of the easiest ways to buy, sell, and hold cryptocurrencies, which earns it the first spot on this list. With Coinbase, you can connect to a U.S. bank account and easily transfer dollars in or out of your wallet. You can use those dollars, or transfer in new ones, to buy and sell. In addition to Bitcoin, Coinbase currently supports Bitcoin Cash, Ethereum, and Litecoin. There are constant rumors of additional currencies like Ripple getting support from Coinbase as well.
While the big upside of Coinbase is ease of use, that is offset with some worries about security. Mt. Gox was at one point the dominant platform for Bitcoin and other currencies. That is until it was hacked and lost nearly half a billion dollars in user currency. But Coinbase did learn from Mt. Gox's loss, and has very firm security in place, and regularly updates and improves the entire user experience.

Bitcoin Wallet.
Bitcoin Wallet is easy to use and reliable, while also being secure and fast. Its vision is de-centralization and zero trust; no central service is needed for Bitcoin-related operations. The app is a good choice for non-technical people.
Control over your money.
This wallet gives you full control over your bitcoins. This means no third party can freeze or lose your funds. You are however still responsible for securing and backing up your wallet.
This wallet uses SPV and the Bitcoin network. This means very little trust in third parties is required when verifying payments. However, it is not as secure as a full node like Bitcoin Core.
This wallet is open-source and built deterministically. This means any developer in the world can audit the code and make sure the final software isn't hiding any secrets.
This wallet is loaded on mobiles where apps are usually isolated. This provides a good protection against malware, although mobiles are usually easier to steal or lose. Encrypting your mobile and backing up your wallet can reduce that risk.
Prevents spying on your payments.
This wallet makes it harder to spy on your balance and payments by rotating addresses. You should still take care to use a new Bitcoin address each time you request payment.
Discloses limited information to peers.
Peers on the network can log your IP address and associate your payments together when receiving or sending payment.
Tor not supported.
This wallet does not let you use Tor to prevent attackers or Internet service providers from associating your payments with your IP address.
Full control over fees.
This wallet gives you full control over fees. This means that this wallet allows changing the fees after funds are sent using RBF or CPFP. This wallet also provides fee suggestions based on current network conditions so that your transactions are confirmed in a timely manner without paying more than you have to.

Types of Wallets.
There are many different ways to use Bitcoin and so there are many different types of wallets:
Online bitcoin wallets. Wallets that can be accessed on the web from any internet connected device. Bitcoin hardware wallets. Physical devices designed to secure bitcoins. Software wallets. Wallet applications downloaded to your phone, computer or tablet. Paper wallets. Bitcoin private keys printed from an offline computer.
By the end of this article you'll understand Bitcoin wallets and have a better idea about which type is right for you. Here are some factors to consider:
On the go? If you are making payments in person and not online then a mobile wallet like Copay (iOS & Andro >
Atomic Wallet.
Atomic Wallet is a fully decentralized, non-custodial multicurrency wallet, supporting over 300+ coins and tokens. Atomic provides an interface that allows you to not only manage, but also exchange and buy cryptocurrencies without using external services. The wallet has a built-in decentralized orderbook enabling users to exchange BTC, LTC and QTUM using the Atomic Swap technology. Atomic Wallet provides users with a 12-word mnemonic seed, so they get full access to their funds. All private keys are encrypted on an end device.
Copay.
Copay is a Bitcoin wallet by Bitpay and available on iOS, Android, Windows Phone, Linux, Max OS X, and Windows. Because Copay is available on multiple platforms, it's easy to use the same wallet or accounts across multiple devices.
Copay's simple, clean user interface makes it a good choice for new Bitcoin users. Copay is also a good option for businesses due to a shared account feature, which requires a certain number of users to sign each transaction. Two co-founders, for example, could create a 2 of 2 wallet where both will be required to sign each transaction.
Hardware Wallets.
Hardware wallets are small computers or smartcards built with the sole purpose of generating Bitcoin private keys offline. Hardware wallets securely sign transactions in the same offline environment.
COLDCARD Wallet.
Coldcard is an easy to use, ultra-secure, open-source and affordable hardware wallet that is easy to back up via an encrypted microSD card. Your private key is stored in a dedicated security chip. MicroPython software design allows you to make changes. It goes above and beyond, by giving you the option to sign transactions fully Air-Gapped/Offline via MicroSD (PSBT-BIP174)
Coldcard is different than other wallet. No specialized software required. It accepts standard PSBT transaction (BIP 174) stored on an MicroSD card. No companion 'app' on your computer, works with the major wallets already (Electrum, and more to come). It's cheap! Simple packaging, plain design, no fancy boxes, no redundant cables. It's ultrasecure! Real crypto security chip. Your private key is stored in a dedicated security chip, not the main micro's flash. Easy back-up! MicroSD card slot for backup and data storage. This allows truly offline signing, by transferring the unsigned/signed transactions on sneakernet. Open source software design runs Micropython and you can change it.
Ledger Nano.
The Ledger Nano is a smartcard based hardware wallet. Private keys are generated and signed offline in the smartcard's secure environment. The Nano is setup using the Ledger Chrome Application. A random 24-word seed is generated upon setup and backed offline by writing it down on a piece of paper. In case of theft, damage or loss, the entire wallet can be recreated with the seed. A user selected PIN code is also assigned to the device to protect against physical theft or hacking.
The Ledger Nano may be used on any computer, or Android phones with Mycelium or GreenBits.
TREZOR.
The TREZOR differs from the Ledger Nano in that it's a very tiny computer rather than a smartcard. Private keys are still generated offline.
TREZOR also generates a 24-word seed upon setup. The TREZOR has its own built in screen where the seed is displayed and copied down during backup. Since the TREZOR is an offline device it offers extra security since the seed isn't displayed on an online computer.
An additional passphrase can be added to the 24-word seed. This provides extra protection, since anyone who finds someone else's 24-word seed is free to access the funds. If the optional passphrase is added, an attacker still wouldn't be able to access funds without both the seed AND the passphrase. If the passphrase is forgotten, it cannot be recovered.
OPENDIME.
The first Bitcoin Bearer Bond or called a Bitcoin Stick. Opendime is a small USB stick that allows you to spend Bitcoin like a dollar bill. Pass it along multiple times. Connect to any USB to check balance. Unseal anytime to spend online. Trust no one.
Acts like a read-only USB flash drive. Works with any computer, laptop, and phone.
A QR Picture and Text file inside contain Bitcoin address and support.
The private key is generated inside the device, and is never known to any human, not even you!
The Bitcoin world changes fast but Opendime is built on the fundamental Bitcoin features that have not changed in five years.
Give an Opendime to anyone and they don't need to worry that you can take back the funds later.
You have got the private keys in the device. This is physical Bitcoin as it was meant to be to just hand it to someone and they have got it.
Pass it on multiple times! Simple as a handshake. No miner fees, no confirmation delays.
Uses Bitcoin message signing, normal (non HD) bitcoin payment addresses and private keys in WIF format.
Ledger HW.1.
The Ledger HW.1 is a more affordable version of the Ledger Nano.
Ledger Unplugged.
The Ledger Unplugged is a credit card-size wireless hardware wallet. Private keys are generated offline. Transactions are signed on the device and sent to a mobile phone via NFC.
The Ledger Unplugged is ideal for everyday use, since the device fits perfectly into wallets and no OTG cable is required.
Online Bitcoin Wallets.
Online Bitcoin wallets, or web wallets, store your private keys online. Wallets can only be accessed with a user-set password.
GreenAddress.
GreenAddress is a multisig web wallet, with apps available for Chrome, iOS, and Android.

Airbitz manages accounts with usernames and passwords, but doesn't have access to your funds. This type of account creation is easier for less technical users who may have trouble backing up or understanding HD seeds.
GreenBits.

Mobile Wallets for iOS.
breadwallet (iOS)

Airbitz.
AirBitz is also available in the App Store.
Desktop Wallets.
Desktop wallets are software wallets that are downloaded and installed on your computer. The desktop wallets below are available on Mac OS X, Windows, and Linux.
Paper Wallets.
Paper wallets were the standard method of cold storage before hardware wallets were built. Paper wallets are private keys printed out on a piece of paper. If generated and printed with a secure, offline computer, paper wallets are secure cold storage.
The main problem with paper wallets is it can be inconvenient to create and print a new wallet each time you send funds to cold storage. However, it's possible to bulk print paper wallets to save time and eliminate address reuse. Our cold storage guide explains step-by-step how to create a secure paper wallet.
Best Practices.
Bitcoin lets you control your money, meaning you are responsible for both your money's security and your financial privacy. Here are some steps you can take to ensure your privacy and security:
Control your private keys.
Services like Coinbase and Circle offer "Bitcoin wallets", but in reality control your private keys. It's best to use a wallet where you control your private keys. This is the only way to have full control of your funds and not have to rely on third parties for security.
Protect your privacy.
Each time you request blockchain data from a wallet, the server may be able to view your IP address and connect this to the address data requested. Each wallet handles data requests differently. If privacy is important to you, use a wallet that downloads the whole blockchain like Bitcoin Core or Armory. Tor can be used with other wallets to shield your IP address, but this doesn't prevent a server from tying a group of addresses to one identity. For more information, check out the Open Bitcoin Privacy Project for wallet rankings based on privacy.
Don't reuse addresses.
Most Bitcoin wallets today automatically create a new address for each transaction. Since all Bitcoin transactions are public, address reuse makes it easy for others to group transactions and understand which payments are connected to one identity.
Use different wallets for different sums of money.
Just like you don't walk around with your savings account as cash, there are different Bitcoin wallets that should be used depending on how much money is being stored or transferred. Secure wallets like paper wallets or hardware wallets can be used as "savings" wallets, while mobile, web, and desktop wallets should be treated like your spending wallet.
Create multiple secure backups.
Users should create multiple backups of their wallets. Backups should be kept in separate physical locations in the case of fire or water damage. Paper wallets can be laminated or written in metal for extra protection.
How to Store Bitcoins.
Earlier it was mentioned that there are four types of Bitcoin wallets: online wallets, hardware wallets, software wallets, and paper wallets. These four categories can be broken down further into different kinds of storage and security:
