Which allows you to receive, send, or monitor digital currencies. There are some types of wallets, some of which are only for single cryptocurrency, some are for several coins.cryptocurrency.
The function of the crypto wallet is more or less the same as a real leather wallet, it functions to store the cash we have. It’s just that the crypto wallet does not place physical coins like physical money in your leather wallet.
In cryptocurrency, there is no physical form but only a number that has the same value as flat money. The cryptocurrency wallet has a unique address that can be shared publicly. Which allows one to send cryptocurrency using that address.
Each address has a unique combination of letters and numbers, so if someone sends digital currency to that address, there will be no mistake in sending the money.

How does crypto wallet work?
In general, a cryptocurrency wallet is a software where you can see the total balance available. And also you can make transactions, you can transfer some crypto coins to other users using public addresses.
The public address is a specific account number in the form of a combination of letters and unique numbers. If a user will transfer some cryptocurrency values to you, you must give him a public address.
Public addresses are like bank account numbers, where even if you share them with others, they cannot access what is in the account. Private key functions like a PIN in your account, you have to protect this from other people.
Because if someone else knows the private key of your wallet, then the security of your crypto wallet is in danger. They can access your account and do something outside of your wishes.

Public key 1Q9RVP1yQSB3taGriKqqFQKrbhYxhxQFSi
If at first glance, they look different, it is true, but blockchain technology software can recognize that the two are interconnected. Then there is no need to be a serious problem, as long as you can use the crypto wallet safely, it is enough to start investing in cryptocurrency.
Types of wallet cryptocurrency
Some crypto wallet providers have different ways to be able to access wallet addresses. There are several types of cryptocurrency wallets, some of which are
The hot and cold wallet
A hot wallet refers to the type of crypto wallet that is connected through the internet.
For example, you send some funds to your crypto wallet at an exchange, like as at Binance, then you deposit funds to an account called a Binance hot wallet, this is easily accessible and makes it convenient.
Cold wallet refers to the type of crypto wallet that is not connected to the internet.
They have a physical store for offline keys, so cold wallet security standards are safer than hot wallets. Because hackers will not easy to access them.
Software wallet cryptocurrency
A software wallet is a type of wallet that is connected to the internet or can be said to be a hot wallet.
In general, a software wallet included
- Desktop wallet, you need to install software on your desktop to be able to access your wallet.
- A web wallet or online wallet, it is stored in the cloud and you can access it with the internet with any device, the private key is stored in the cloud.
- Mobile wallet, you need to install software on your smartphone to access the wallet.
Hardware wallet cryptocurrency
Hardware wallets are one of the cold wallets, this is physical storage such as USB. Providing higher security because it is not directly connected to the internet, so it is safer from hacker attacks.
But the risk is when the hardware gets an error and is difficult to access. To enter the wallet you must connect to the device then connected to the internet.
A paper wallet is a type of crypto wallet where private keys and public keys can be printed in the form of QR codes. So this includes a cold wallet because it is not connected directly to the internet.
With this paper wallet, from a random number generator will generate certain printable code. If you want to make a transaction you must enter the private key or use QR code scanning.
But the weakness of this wallet is that you have to send all balances once sent, you cannot send in part. For example, you will send 2BTC, and you have 10 BTC, then you must send 10 BTC to the web wallet or mobile wallet, then you can send 2 BTC.
What is the most secure wallet cryptocurrency?
In terms of security, a cold wallet is the safest crypto wallet, because it is not connected to the internet. So you do not need security from third parties, you store it on any device offline, so it cannot be reached by hackers.
However, the cold wallet does not mean that it does not get a problem. If the firmware on the device has a problem that makes it difficult to access. You will lose your private key and this will lose your wallet access.
Meanwhile, hot wallets, they are connected to the internet and this is vulnerable to hackers. So you have to pay attention to the security wallet of the provider whether they have good security standards or are quite risky. With a high-level layer level of security will certainly make it difficult for hackers to steal private keys. Even though the online wallet or hot wallet is vulnerable to hackers.
You must be smart to take steps to secure your wallet.
- Backup wallet. Store only a certain amount of funds for online purposes only, you can place most currencies in an offline wallet such as Ledger Nano or paper or USB.
- Keep software updated. Keep the software up to date so that you get better security, not only wallet software but also your device.
- Add a layer of a security layer, with a high level of a security layer, will be better, using a complex password and choosing a wallet that has a good reputation and adding a layer of security such as 2FA and pin code will certainly make the wallet safer.
Store the password offline and don’t lose it, this is just in case.

Using crypto digital currency has a lower fee than the fee from the bank transfer fee. Maybe this is one of the reasons why many people want to use digital currency as a method of online payment.
You can even set the number of fees you will spend when sending money. But the lower the fee will get lower priority so that your transaction will be confirmed, your transaction may be confirmed for an hour or even a day.

Is the wallet cryptocurrency anonymous?
The wallet is pseudonymous, like anonymous but not really. All crypto wallet transactions are stored publicly and permanently on the blockchain.
You don’t find your home address there, but data such as your wallet address can be traced to your identity in several ways.
