Choosing a is no longer just a matter of choice in favor of security or simplicity. Using different wallets for different purposes is becoming common same as using of different bank accounts when working with currencies like a US dollar or Euro.
A few years ago, there were several major types of wallets and new developments in this sphere continued to appear. Nowadays, the process of choosing a has become more complicated then before. Here we will try to carry out a brief classification of wallets according to their purpose.
A is a pair of two large and complex numbers. The first one is a public key. It is your or adress to send or receive Bitcoins. The second one is private key. It’s encrypted and not intended for public access. A private key serves to confirm transactions on .
Types of bitcoin wallets

- Web-wallets (online wallets);
- Mobile (installs on smartphones etc.);
- Local (installs on a PC or a laptop);
- Hardware (as a separate device);
- Paper.
In addition to preveous classification of wallets, there is also a division into cold or hot wallets
You need to download full and constatly upload new blocks for using cold . This type of has a number of drawbacks for the average user:
- download takes a lot of time — more than a day when first used. The entire transaction registry is loaded starting from the first day of bitcoin existence
- The volume takes about 100 GB of space on your HDD device because it includes the entire bitcoin’s blockchain.
- There is a risk of a complete and irretrievable loss of the itself if the hard disk is damaged. So you need to make a reserve copy for safety on another device.
You do not need to download the entire history of the transactions while using a hot . You can operate with all the necessary data on third-party services. This method is convenient when using the on a smartphone. But security level is much worse than cold because you will need to entrust a part of the necessary data to third-party services.
Web-wallets (online wallets)
Online wallets has several advantages:

Local wallets
As we said earlier, wallets are divided into cold and hot. Now let’s discuss a couple of examples.
Among the cold wallets, we consider Core, as well as an application that extends its functionality.
Core.
If you are not sure which to use, then choose Core. This application has a high-level security, confidentiality and it works stably. This is an official client but it has a large resource intensity. Experts advise to keep it constantly on for supporting the system. It allows other nodes to connect to you.

The details of the coin are displayed: transaction history and the current address with a convenient copy to clipboard icon.

.
It is very similar to Jaxx, the only significant difference is the “e-mail backup” function when the Seed-key of 12 English words sent to the mail in encrypted form.

Paper wallets
A paper is a paper where private and public keys are printed as a QR code. To use these keys, you have to scan them. Paper wallets are usually better and safer than any other type of wallets. Creating a paper does not require a lot of effort or technical knowledge. A few simple steps will significantly secure your coins.
