How to Keep Your Crypto Safe and Secure?

If you own any cryptocurrencies, the first thing that you should think about is how to keep your crypto safe and secure. Security is an aspect that is often overlooked until shit happens. (My website just got hacked yesterday, so I am very well aware of the pain)

I used to think it is much convenient and easy to just leave your crypto funds on the exchange. After all, I have never experienced any loss of crypto funds from hacking incidents. So why go through the cost and hassle of buying a hardware wallet like Ledger Nano S? That was my original thoughts. But that has changed and here is why.

1. Best Way to Store Your Cryptocurrency

The best and most secure way to store your cryptocurrency is to get a hardware wallet like Ledger Nano S. Ledger Nano S is a hardware wallet that stores your cryptocurrencies. It is the number 1 recommended method in terms of security. A hardware wallet means it is a physical device that you can hold and touch.

So what is so special about this physical device called Ledger Nano S? Very simply it stores your private keys inside. When you own cryptocurrencies, you are just owning some private keys. Having access to a private key means you are the rightful owner of the coins. That is how crypto works in general. It is based on Public-key cryptography.

Whenever you want to make any transfer of cryptocurrencies, you have to connect this Ledger Nano to the computer and approve the transaction. So your private keys are NEVER revealed on the internet. Most people got hacked because their private keys got leaked on the internet through scams or hacks.

If people know your private keys, you are gone. Because remember, having access to a private key means having access to the cryptocurrency. It means they have access to all your crypto funds and they will transfer ALL your money out.

It is like people knowing your bank login credentials. The only difference is that bank you still have customer support that could potentially reverse the transaction. In crypto, there is no customer support. If it’s gone, it’s gone. No one can save you.

That is why getting the Ledger Nano S is so important. If you want maximum security on crypto storage, get a ledger. Period. In a sense, owning a ledger is like you are physically holding the private key. NOBODY can transfer crypto out of your wallet unless they stole your ledger and they know your pin password.

2. Difference Between Hot Wallet & Cold Wallet

This method of storing your cryptocurrencies on a Ledger is otherwise known as a “Cold Wallet”. Cold wallet means the things are stored offline. It is just like how you store files in a thumb drive. It is not on the internet and they are stored offline inside a physical device. No one can hack the files unless they stole your thumb drive.

On the other hand, “Hot Wallet” is storing things that require an internet connection. For example, those crypto exchange or desktop wallets are considered hot wallets because the private keys are exposed to the internet. As long as it is accessible through an internet connection, it is a hot wallet.

Hot wallets are much more vulnerable to attacks and hacks. For the simple reason that it lives on the internet. Anything that is “online” is at risk to a certain extent. Hackers are attacking you every single day and these bots are swarming around everywhere. All it takes is one successful hack and you risk losing your entire crypto funds. Don’t learn it the hard way.

While you think big exchanges are safe, they are not. Even Binance & Coinhako has been hacked before. The number of hacks on exchanges is rising every year. As long as your cryptos are on the exchange, it is never safe. You are just trusting these exchanges, who are not cybersecurity experts, to hold your funds securely for you.

A good analogy would be this. Is it safer to store your confidential files on Google Drive (Hot Wallet) or your thumb drive (Cold Wallet)? Just that now we are talking about money. Would you rather store your crypto funds on the hot wallet or a cold wallet?

3. “Not your keys, not your bitcoins”

There is also a famous adage in crypto, “Not your keys, not your bitcoins”. By storing them on exchanges, you don’t own any bitcoins. That is because you don’t have the private keys to those bitcoins. The exchange has it, but not you. Hence the phrase, “Not your keys, not your bitcoins”.

When you store your crypto funds on the exchange, it is just an IOU. Just like how when you store your money in the bank, it is an IOU. The crypto exchange has an obligation to give you whatever amount of bitcoins you have upon your withdrawal demands. That’s it. What you own is just a promissory note between you and the exchange. NOT bitcoins.

Just like how when you buy a gold ETF, you don’t own any gold. You are just owning a share of the trust. Gold ETF are just paper gold derivatives backed by physical gold. But you don’t own any gold at all. That’s why I just sold all my gold ETF and bought physical gold that I can hold and touch. Now I own gold. You can read more about it in my previous post.

Similarly, by buying a ledger and transferring your bitcoins into the ledger, you are taking physical possession and ownership of your bitcoins. This is because you are holding the private key that has access to the bitcoins. If you have the key, you own bitcoin. If not, you don’t.

The core underlying difference is just ownership. Do you want to own them yourself? Or do you want to take on the counterparty risk by entrusting your assets to a 3rd party? Some of such risks include hacks, downtime maintenance, security vulnerabilities and etc.

4. How Are People Storing their Crypto Fund?

In 2020, we are seeing an increasing trend of people using cold storage wallets like Ledger Nano S to store their bitcoins. The above on-chain analysis chart by glass node shows the total balance of bitcoins that are stored on exchanges. You can see that from March till date, the line chart has been falling drastically.

What this means is bitcoins are being moved OUT of exchanges. Usually, that means people are transferring their bitcoins from the exchange into their hardware wallets. Well, I am one of the statistics in the chart.

Additionally, when people start storing bitcoins on a cold wallet, it also means they are HODL-ING for the long term. This is likely because of the bitcoin halving. People realised that the supply of bitcoins has become more scarce and bitcoin is an alternative hedge against money printing.

The only reason people store them on exchanges (hot wallet) is that they are doing some short-term trading. If you are investing for the long-term, it is really a bad idea to keep them on exchanges.

5. How to Buy Ledger Nano S?

*Affiliate Link Disclosure: At no additional cost to you, I will make a commission if you click through and make a purchase.

Because of the above reasons, I just bought a Ledger Nano S last week. I think it is very reasonable that you invest a one-time fee in security to get it right once and for all. Once you move your crypto into the Ledger Nano S, your crypto is safe and secure. You feel more assured and sound. So why not?

Think about the risk at stake. If bitcoin ever goes up to $20k, $50k and your crypto portfolio is worth tens of thousands, what happens if security is compromised? It is definitely a situation you don’t want to get yourself into. The best way to protect yourself is to store your crypto properly in a hardware wallet.

If you are interested in buying a Ledger Nano to store your crypto funds, here is TheBabylonians’s link to it. There are two main types of ledgers on their website. One is the Ledger Nano X and the other is the Ledger Nano S.

How to Keep Your Crypto Safe and Secure?

The one that I bought is the Ledger Nano S. The main difference is just more storage space and some Bluetooth features. If you are just holding bitcoins and a few other altcoins, Ledger Nano S is more than enough. I feel is unnecessary to get the Ledger Nano X. That is almost a $100 difference. But if you hold a lot of cryptocurrencies and you feel storage space is important, then Nano X would be a better pick.

Alternatively, you can choose to buy the ledger on other online platforms. But there is a risk that the Ledger might be tampered with. This has happened before and it is something that you don’t want to get stressed up about. For security reasons, it is best to get it directly from the original manufacturer.

6. How to Set Up Ledger Nano S?

One of the main reasons why I didn’t get the Ledger earlier is because I always thought it is too complicated for me.

However, after buying it and using it personally, I realised it is really simple and user-friendly. There are a ton of tutorial guides out there and I got it all set up in less than 30 minutes. Not difficult at all.

Here is how the steps look like briefly.

There are no batteries on the Ledger Nano S. To power it up, all you got to do is just connect the USB cable to your computer.

How to Keep Your Crypto Safe and Secure?

When you first power it up, it will ask you to set up your pin number and write down 24 random backup words. These 24 words are extremely IMPORTANT and they are your private keys. If people know it, they essentially get access to all your crypto funds. So keep them really safe.

What happens if the ledger got damaged or the company went bankrupt? Not to worry. As long as you have the 24-back up words. You can restore your funds safely using OTHER wallets. Ledger is not the only one, but it is the most trusted and recognised brand in the market.

Your funds are NOT in the device. It is on the blockchain. This is a common misconception. The ledger is just a shell that holds your private keys. If it is gone, you can restore your keys and crypto funds easily using the 24-word backup phrase.

So just write them down on the cards that come together with the package. Then keep the cards in your safe vault. Or Best is to memorize them in your head as I did. DO NOT store the 24 backup words online as that defeats the purpose of owning a ledger. Remember to do everything offline.

After you have set up your pin number and you have wrote down the 24 back up phrases. You are done and ready to go.

7. How to Send Crypto to Ledger Nano S?

The next step is to transfer all your cryptocurrencies OUT from the exchanges into your Ledger Nano S. We want to store them safe and sound in a cold wallet offline.

How to Keep Your Crypto Safe and Secure?

Firstly, you have to download Ledger Live, a dashboard interface which allows you to manage your cryptocurrencies easily.

Secondly, open the Ledger Live and connect your Ledger Nano S to the computer. Then click on the “Manager” under the Menu tab on the left. Finally, just click “Install” on whatever coins you hold. For me is bitcoin and ethereum (ERC-20 tokens), so I already have that installed.

Thirdly, go to “Accounts” under the Menu tab on the left. Then click “Add Account” on the top-right hand corner. I added bitcoin and Ethereum. These accounts are your wallets to send or receive cryptocurrencies.

How to Keep Your Crypto Safe and Secure?

Finally, just click on the “Receive” button and Ledger Live would generate a public address for you to send your bitcoins to. The last step is to go to your exchange and send your bitcoins to the public address that Ledger Live has generated for you. The best way is to just copy and paste the address.

If you are holding ETH or some other ERC-20 altcoins, then just go to your ethereum account and click the “Receive” button to generate a public address. Then send your ETH or ERC-20 tokens from the exchange to the generated public address on Ledger Live.

For example, I hold some KNC (Kyber Network) tokens and I sent them to the Ethereum address on my Ledger Live. All the ERC-20 tokens would be stored under the Ethereum address as seen above.

And That’s it! You are done! That is how you move cryptocurrencies from exchanges to Ledger Nano S. It is really simple. More importantly, that is how you store your crypto funds properly to ensure that it is safe and secure. After you have completed all the above steps, just sit back, relax and HODL. You are all good and you there is nothing else to worry about. Just remember to keep your 24-word backup phrase safely or commit it to memory.

Once again, “Not your keys, not your bitcoins”.


  1. Curious. Aren’t you connected to the internet via the Ledger Live app when you perform the transactions to transfer coins from the exchanges to the hardware wallet? Wouldn’t someone be able to intercept the “public address” generated by the app for the transfer and use that to effect illegal transfers the next time you connect the hardware wallet to the internet? Isn’t this then considered a “hot wallet”?

    How different would this be with wallet apps downloaded onto phones? Are the latter considered hardware wallets as well?

    • The difference is that after the Ledger Live generated a public address, it would show up on your ledger nano s and ask you to confirm whether the public address is the same as what was generated. So that removes the issue of hackers intercepting and changing the public address.

      And no it is not a hot wallet because your private keys are not on Ledger Live. They are in your physical device. Other wallet apps actually store your private keys on the app itself.

      yea, for example, MEW also stores your private keys on your phone. So your phone is like a hardware wallet.

  2. What happens if the private keys in the device gets corrupted or the device has a hardware failure? Also, if the device is lost or stolen, what is the risk that an authorised person can get access to your private keys? Could you recover the private keys and disable/wipe out the device remotely, assuming you have discovered the lost/theft early?

    • Hey Victor,

      If the device has a hardware failure. You can always restore your crypto funds on other hardware wallets as long as you remember the 24-word backup phrases.

      If your device is stolen, the person would still need to know the PIN number that you set on your Ledger before he can get in. Meanwhile, if it gets stolen, you should immediately transfer out all your crypto funds to another wallet ASAP.

      An analogy would be like a thief who stole your bank card but doesn’t know the PIN number, he can’t withdraw out the money.

    • I am staking my ICX with ledger. It depends on what coins is that. Some have locking period like ICX (about 9 days). But if there is no locking period, you can just withdraw and deposit out of your ledger as and when you want.

    • When you want to cash out, just send your cryptocurrencies from the ledger to Coinhako, then cash out from there directly.

  3. Hi
    Could you advise on how to send from coinhako to ledger?
    is it the same as sending from coinhako to others?
    I tried to do but there is no place where i can insert a wallet link?
    Let’s say if i send to the public link generated then there will be a network fee. Is it how it should be?

  4. Hi may I check is there any transcation fee when transfer coin from ledger to coinhako?
    Tempting to get the one but check online the transaction fee can cost around $4 – $8 per transaction.Not sure if its true Newbie?Newbie to crypto here 🙂
