Cryptocurrencies & security
The world of cryptocurrencies is still in its infancy. Even though Bitcoin is now 10 years old, the general public is starting to hear about it in 2017 with the bubble that brought Bitcoin to nearly $20,000.
The principle of cryptocurrencies is that YOU ARE THE BANK. The technical operation is based on public and private keys, so it is essential to learn about the best way to secure your coins. Whether it is Bitcoin, Ethereum, Litecoin or Monero, what you need to know is that if you don’t have your private keys, you don’t have your coins.

How to store Cryptocurrency Safely in 2020
For the security of your Bitcoin or other ERC-20 tokens, it is essential to use a hardware wallet. This method is called “cold storage” because your corners are not on your hard drive or on the exchanges.
One product allows to store cryptocurrencies in “cold wallet” mode offline: The Nano S or Nano X ledger. This key also allows to make U2F key but is a little more restrictive to use. The advantages of such a security level product are numerous:
Security: your private key that gives access to your assets is never exposed, it is protected inside a chip secured by a PIN code. The Nano S supports more than 20 cryptocurrencies, including Bitcoin, Ethereum, Ripple and many other altcoins, allowing you to manage multiple assets with the same hardware portfolio.
Simplicity: The device is controlled by only 2 buttons, and all actions can be checked on its screen.
Access to exchanges
If you are active in the markets, it is necessary to have cryptocurrencies on the exchanges. The best known are Binance or Kucoin to trade a large number of crypto.
Like an online service like Google or Dropbox, Binance allows you to use a U2F security key for certain actions: access the exchange, make a withdrawal or reset your password. This kind of security ensures that even if your account is hacked, your cryptocurrencies are safe. A real plus that should be offered by a larger number of exchanges!
