Blockchain technology has given cryptocurrencies a reputation of being secure currencies. The media are constantly talking about the theft of virtual currency, sometimes at an alarming rate. These thefts usually occur through transfers or simply by trapping the owner. While attacks may be difficult because of the decentralization of blockchain, it is still possible to attack holders of these currencies.
If you're using an online crypto exchange, it is possible that you don't actually have your coins at the protocol-level. The platform holds your funds as well as the keys to transfer them. If you want to withdraw the currency you ask the exchange for a transaction.
These services are all online, so it is possible for a third party to disrupt the transfer. It is possible to transfer crypto-currencies from your computer to the USB keys or hard drives that are designated for this purpose.

The Cold Wallet :
A cold wallet can be described as a physical wallet that is completely offline and stores currencies. It is usually a USB key. These tools are not connected, making them less vulnerable to attacks than secure applications. While there may be panic on a platform, currencies can remain hot on the key. To provide additional security, some companies offer an encrypted wallet. This is the best solution if the value of the assets you have to store is very high.

Use a complex password
Although it seems like a sensible suggestion, we often forget that hackers are most interested in crypto wallets. There are many ways that cybercriminals can get your passcode back. For example, a brute force attack uses software to attempt as many combinations as possible before finding the right one. The most important criterion is the length of the password. You can choose a sentence for example like "Jaimelatartealapomme". Then sprinkle numbers and signs, and it gives "JaIm3latartealap0mm%". This password is difficult to crack.
Enable two-factor authentication
Double authentication should be included in any wallet you choose. Double authentication adds an additional layer of security to your funds. It requires verification before you can perform certain operations such as login, withdrawals, or remittances. If someone attempts to access your wallet, you will be notified immediately. Most online wallets provide double authentication. These tips will ensure that your currencies are secure. It is up to you to avoid falling for phishing emails by hackers.
