When you transfer cryptocurrency funds, the transactions are recorded in a public ledger. Cryptocurrency, or crypto, is virtual or digital assets purchased with real money ($, £) traded on blockchain technology. Cryptocurrencies, like Bitcoin and Ethereum, are different from stocks and real money. Crypto is not regulated like stocks or insured like real money in banks. How do cryptocurrencies transfer value digitally between two trustless parties, then?
This is what makes blockchain transactions secure and nearly impossible to alter. Tens of thousands of computers must verify a single transaction or entry. If there’s a disagreement among computers, the transaction will be voided.
Otherwise, fraudsters may pose as legitimate virtual currency traders or set up bogus exchanges to trick people into giving them money. Another crypto scam involves fraudulent sales pitches for individual retirement accounts in cryptocurrencies. Then there is straightforward cryptocurrency hacking, where criminals break into the digital wallets where people store their virtual currency to steal it. Once you have purchased cryptocurrency, you need to store it safely to protect it from hacks or theft. Usually, cryptocurrency is stored in crypto wallets, which are physical devices or online software used to store the private keys to your cryptocurrencies securely. Some exchanges provide wallet services, making it easy for you to store directly through the platform.

Unlike government-backed money, the value of virtual currencies is driven entirely by supply and demand. This can create wild swings that produce significant gains for investors or big losses. And cryptocurrency investments are subject to far less regulatory protection than traditional financial products like stocks, bonds, and mutual funds.
In order to preserve the integrity of the ledger, cryptocurrencies require consensus, or agreement, by a majority of users of that cryptocurrency before it can be added to the ledger. Different cryptocurrencies have different ways of achieving this consensus, as well as rewards for being the party chosen to add an entry to the ledger. That’s why cryptocurrencies use a distributed blockchain that allows anyone to verify that the token is actually owned by the person who is sending it.
Once every node has checked a block, there is a sort of electronic vote, as some nodes may think the transaction is valid, and others think it is a fraud. Instead, the computers participating in the network are tasked with verifying and facilitating each “block” (i.e., entry or transaction) within the chain. In some cases, all the computers work together to verify and facilitate each block action. In addition, transactions require a two-factor authentication process. For instance, you might be asked to enter a username and password to start a transaction. Then, you might have to enter an authentication code sent via text to your personal cell phone.
