Owning your private keys gives you much more power and control, but it also comes with the needs of taking care of their security. Many tools are available to manage your keys, usually called “wallets”, but not all of them are secure. There are 4 different type of wallets you could use to manage your assets:
Online wallets are online services that enable you to access your crypto assets from any browser that’s connected to the internet. When you leave your crypto assets on a cryptocurrency exchange platform, you’re actually using the platform’s online wallet.
The biggest advantage of online wallets is that they are easily accessible from any computer or other device with an internet connection.
Being online is also their biggest disadvantage asthey can become targets for hackers. Moreover, in most of the cases, you do not keep control of your private keys: they are controlled by the wallet provider.
Software wallets are applications for managing cryptocurrencies that can be installed on your computer or smartphone.
You remain in control of your private keys which are not shared to nor controlled by a third-party.
Unfortunately, since a software wallet is installed on your PC or smartphone, it is still connected to the internet which exposes your private keys to hackers.
Vulnerabilities of modern PCs and smartphones are well known, and if you keep your private keys there it’s just a matter of time before you’ll get hacked and lose everything.
A paper wallet is an offline mechanism for storing crypto assets. As suggested by its name, the process simply involves printing the private keys and its corresponding addresses on a paper sheet.
This is a simple way to store your cryptocurrencies keys offline. It requires paying great attention and care to this paper.
If your paper wallet gets lost or destroyed, you will permanently lose the access to your crypto assets. Also, processing a transaction with a paper wallet can be tedious and unsafe: you will need to manually enter your keys in a transaction tool, typically by using your computer’s internet browser which could expose the keys to a cyber attack.
A Hardware wallet is an offline storage option for private keys. This is a physical device that allows you to store the private keys in an offline and secure storage, and generally also enables you to verify the transaction details on the device screen.
With a hardware wallet, even if a hacker succeeds in getting control of your computer, he will not be able to steal your private keys and access your crypto assets. Your private key is kept offline and limits the risk of hacking.
As a result, hardware wallets are widely considered to offer the most secure wallet option.
