The most important benefit of Bitcoin (and other cryptocurrencies) is the fact that you and only you have control over them. No one, like a bank or government, for example, can take them from you.
But with great power comes great responsibility. Because only you control your funds, if thing go south, there’s no one to rely upon and no one to help you. If you mess things up, you can only blame yourself.
Therefore, keeping your coins safe is the highest priority of any cryptocurrency owner. Here is the list of main alternatives where to keep one’s coins, from the worst to the best option.
Level of security: LowRecommended storage value: $0Recommended wallets: not recommendedUsability: You don’t have full control over your funds
99% of all cryptocurrency hacks happened at exchanges, so it’s by far the most dangerous place to keep your coins. Even transferring a large amount of coins for a short period of time may be risky, because an exchange may have covered up that they have been hacked. Just remember what happened with Mt. Gox. Not to mention that you usually have to go through painful KYC process and the exchange may freeze your funds in case they don’t like something.
Level of security: MediumRecommended storage value: 1k$-10k$Recommended wallets: BlockChainUsability: Best for everyday use for both PC and mobile
Online wallets have better security than exchanges, since most of them keep customers coins separately from each other and thus each account has to be hacker individually. However, since they are accessible online anyone can try to hack them. There is a huge difference between online wallets. Some may offer decent security with two-phase-authentication, while others are as risky as exchanges.
Level of security: HighRecommended storage value: 10k$-100k$Recommended wallets: Bitcoin Core**Usability: For more advanced users**
Desktop wallets have generally high security and the only real risk is your computer being hacker remotely or a trojan virus stealing your information. Having your desktop wallet on an offline computer will make it almost unhackable and vulnerable only to physical theft.
Level of security: Very highRecommended storage value: +1M$Recommended wallets: Trezor or LedgerUsability: Good for everyday use or long term storage
Hardware wallets are very safe. Realistically there’s no chance of someone hacking them. However, there’s one weakness: the recovery seed. 100% of all theft from hardware wallets happen because the recovery seed gets stolen. It’s advised to keep the recovery seed in your home safe or at security deposit box in the bank.
Level of security: Highest possibleRecommended storage value: +1M$Recommended wallets: bitaddress.org**Usability: Only for long term holding**
An old school method of keeping your Bitcoins safe that still works. With a paper wallet you simply write down the private key of your Bitcoin wallet, which has the strongest possible security. The only risk of this is that someone will steal the paper where you wrote down your private key, therefore it should be kept at your home safe or at security deposit box in the bank.
And most important! Don’t tell anyone how much money you have and where you keep your Bitcoins. Don’t become a target.
