Is it Possible to Hack Crypto? Each token has a private key that the owner or custodian holds. Because of encryption, hacking the token and number would take years.
Despite the hazards, investors from over the world have flocked to Bitcoin and other cryptocurrencies due to the promise of quick profits. Bitcoin’s success has spawned countless imitators, followers, and enthusiasts. Not to be outdone, thieves also discovered possibilities, for where there is a promise of wealth, there is a chance to steal it.
There are vulnerabilities that hackers can exploit, so your cryptocurrency can be hacked; however, this is only possible under specific conditions. Consequently, how can you safeguard yourself and your investments?
- Cryptocurrency is a digital currency that doesn’t have a central bank and uses cryptography to protect transactions and information about who owns what.
- A blockchain is a digital ledger that keeps track of all the transactions that happen with cryptocurrencies.
- Because of how blockchain technology works, it’s almost impossible to break into one. But there are flaws outside of the blockchain that gives thieves a chance to steal.
- Hackers can steal cryptocurrency from the wallets and exchange accounts of people who own cryptocurrency.
Security for Blockchain
Bitcoin came out in 2009. It is a decentralized digital money, meaning it is not managed or controlled by a single individual, group, government, or other entity.
Blockchains record and verify all cryptocurrency transactions. Transactions, pseudonymous addresses, and amounts are public. However, scripts, programming, and an automated transaction validation mechanism prevent anyone from adding or changing entries in these public ledgers.
How Is a Blockchain Secured?
Cryptography and consensus procedures secure blockchains. Blockchains encrypt transaction data and include previous block data in each block. Encrypted data links the ledger. New blocks strengthen it.
Therefore, an existing blockchain cannot be “hacked” in the conventional sense, wherein malicious code is added to the chain, or someone brute-forces their way into the network and begins making changes.

How Can Someone Attack a Blockchain?
By influencing a blockchain’s hash rate, an attacker or group of attackers might gain control. They can launch a 51% attack if they control more than 50% of the hash rate. This lets them modify blockchain-unconfirmed transactions. Six confirmations make transactions successful.
If you have a friend with 1 BTC, the first confirmation would be in one block. This block’s information is transferred to the subsequent block, confirmed, and closed. This is the second confirmation. The network needs four more times to process the transaction. 51% of attacks reverse unprocessed transactions.
Attackers could then use unconfirmed transaction tokens. They can send money to anonymous addresses, and the altered blockchain will behave as they programmed.
Where Hacks of cryptocurrency take place
Blockchain tokens represent cryptocurrency ownership. The owner or appointed custodian holds the private key for each token. The token and number could be hacked, but the encryption would take years to crack.
Encryption weakens cryptocurrency and blockchain’s private keys and storage. Cryptocurrency industry saying:
Not your keys, not your coin.
If you don’t control your crypto’s keys, you can’t control what happens to it, regardless of the conditions. A custodial connection between the key owner and the key holder provides that entity control over your cryptocurrency.
Most wallet hacks and thefts include private keys. Wallets on mobile devices and PCs store all private keys. You can write them down or store them on USB drives.
Electronic and software wallets are either online or offline (cold). Hot and cold storage solutions offered by cryptocurrency exchanges are custodial since they keep your keys.
Hackable devices and software. Application and device wallets store private keys, so hackers can steal cryptocurrency.
Despite their claims, custodial key holders are vulnerable. Exchanges store liquidity and customer private keys in cryptocurrency. Hackers target them.
Exchanges are robbed for bitcoin keys. Unless an exchange hacks your private keys, your cryptocurrency is protected.
How to Keep Your Digital Currency Safe
You can keep your cryptocurrency from being stolen by taking a few simple steps. The most important thing is to know where your keys are kept, how you and other people can get to them, and what you can do to make them hard to get to.
Wallets are hot, cold, locked, or unlocked. Internet and device-connected wallets are the least secure. Keep your keys off linked devices for safety. If it is connected and an application has access to your keys, it can be compromised.
Contrary to what ads and reviews of cryptocurrency wallets say, you don’t need a device made by a company to use as a wallet. You can also use a USB drive with encryption. But USB connections can get worse over time, and once a cold storage device is connected to a computer or other connected device, it becomes a hot storage device and stays that way until it is unplugged.
Cold wallets that don’t hold your money are the safest. These can range from a sheet of paper with the keys written on it and stored in a safe to a device with passkeys and further encryption. Paper wallets are only good for short-term use because they are easy to tear.
There are many products that offer security and convenience for your Bitcoin or other cryptocurrencies, but the best way to keep your crypto safe from hackers and thieves is to remember a few simple rules:
- Don’t put your keys in the wallet on your phone or any other device that can connect to the internet.
- Always keep your private keys in cold storage.
- Don’t give your keys to someone else to store unless you’re okay with the risks.
- If you want to use your cryptocurrency, you should only move the keys you need to your hot wallet, do your transaction, and then immediately take the keys out of your hot wallet.
- Keep your cold storage method in a safe place without a wired or wireless connection where the humidity can be controlled.
- Check on your devices every so often to make sure they aren’t getting worse. If they are, move your keys to a new place to store them.
- Don’t let anyone else use your private keys.
