What is Crypto? How to Explain Cryptocurrency to a Child

What is Crypto? Its Relationship with Blockchain and Encryption

When we ask "what is crypto," the first thing we need to understand is the relationship between crypto and blockchain. The term "digital currency" is often used as a translation for "cryptocurrency" on search engines, but this isn't entirely accurate. In reality, cryptocurrency refers to digitally encrypted currency, and the encryption factor is the biggest difference. The dollars in your bank account are considered digital currency, but the difference between them and cryptocurrency is that cryptocurrency lives on the blockchain and requires the blockchain to function.

Understanding the relationship between blockchain and cryptocurrency is crucial. We can simply explain this relationship using the analogy of a house. Cryptocurrencies are like the owners of the house, the blockchain is the house itself, and tokens are the guests visiting the house.

However, in this house, there isn't just one or two people responsible for it. This house is decentralized, meaning everyone in the house is responsible for it. Everyone in the house works to generate the money used to maintain the house. This is essentially mining on the Bitcoin blockchain in simple terms.

But there are blockchains like Ethereum that differ in nature from Bitcoin's blockchain. How can we explain them simply? Ethereum is known for building and developing smart contracts and decentralized protocols, which means it aims to develop something similar to Google Play or the App Store.

Imagine the house example again, but now the house owners (Ethereum currency) are renting out rooms in the house to different projects. This is done to build and develop their own decentralized projects within these rooms. Because there are many rooms in the house, back doors were created to enter and exit the house easily without severe congestion around the main entrance. These are Layer 2 solutions in simple terms.

What Makes Crypto Currencies Special?

Now you know that cryptocurrencies live on the blockchain, but to fully understand "what is crypto," we need to know what distinguishes them from fiat currencies.

Cryptocurrencies are encrypted through encryption technology, which means they are more secure than regular digital currencies and therefore very difficult to hack. Remember the house example? To bankrupt this decentralized house, all the house owners would have to go bankrupt since they all work and generate monthly income. This is because of decentralization. The same applies to blockchain. To hack the blockchain, you would need to hack all devices connected to the network and change the information on them, which is completely impossible. This is why cryptocurrencies are secure.

Cryptocurrencies also have the characteristic of encryption, meaning each currency can only be used if you have its private key. This is exactly like your mobile phone - if you have someone else's phone but don't know their password, you won't be able to use it. This greatly increases the security of these currencies.

Blockchain technology is also fast and advanced. Therefore, these currencies can be sent from anywhere in the world to anywhere else in the world within minutes and at a very low cost. If you want to send large amounts of money, you can use a secure network like Bitcoin or Ethereum and pay slightly higher fees. But if you want to send a small amount of money, you can rely on fast networks like Solana or other Layer 1 solutions.

This means that blockchain and cryptocurrencies have three main characteristics: privacy, speed, and decentralization. These features work together to create a financial system that is more accessible, transparent, and efficient than traditional banking systems.

How Can You Buy and Obtain Cryptocurrencies?

When the question "what is crypto" is asked, it's often followed by how to obtain cryptocurrencies. There are several different methods:

• You can obtain cryptocurrencies for free by interacting with different protocols, which is known as an airdrop. This method has become increasingly popular as projects seek to distribute their tokens to early adopters and community members.

• You can also work in the crypto field to receive cryptocurrencies as your salary. Many blockchain companies and projects now pay their employees in cryptocurrency, offering a direct way to accumulate digital assets.

• The most common method is buying cryptocurrencies. Here, there can be several options. You can buy cryptocurrencies through centralized exchanges. This is done after creating an account on the platform, linking your bank account to it, and going through KYC procedures. These platforms offer user-friendly interfaces and are suitable for beginners.

• Another method is trading currencies through decentralized platforms. This is done by creating a crypto wallet like Trust Wallet to buy currencies on decentralized exchanges. This method offers more privacy and control over your assets.

• You can also enter through major exchanges and buy cryptocurrencies through peer-to-peer features. This allows direct trading between users without intermediaries.

• Finally, you can buy Bitcoin through Bitcoin ETFs if they are available and licensed in your country. This option has become more accessible in recent years as regulatory frameworks have evolved.

• We shouldn't forget the possibility of mining some cryptocurrencies like Bitcoin, Litecoin, and Dogecoin. However, mining these currencies has become very costly and unprofitable for individuals in the past period. Therefore, it is more profitable for large companies and projects with significant capital and infrastructure.

Decentralized Finance and Smart Contracts

The final part of answering "what is crypto" is understanding decentralized finance (DeFi) and smart contracts. Smart contracts are simply used to build decentralized protocols for decentralized finance. Decentralized finance is an alternative to the banking system but on the blockchain.

A smart contract can be compared to an ATM machine, but it differs from the regular machine in that it manages itself 100% automatically. It deposits money into people's accounts by itself and withdraws it. It also updates itself and fixes itself if any malfunction occurs. This means that a smart contract doesn't need human intervention to work. This contract can manage an entire company - it just needs to be programmed effectively.

The main purpose of this is to combat the traditional financial system, especially the banking system. This system has become very slow and unreliable. It has also become mired in corruption and bribery due to its reliance on humans. For this reason, many cryptocurrency experts see decentralized finance as the salvation from all this.

However, decentralized finance is often subject to hacks and cyber piracy. This means there must be a competent programmer to program a smart contract with protection and security. This is to preserve depositors' money, otherwise no one will accept dealing with these protocols. The development of secure smart contracts requires extensive testing, auditing, and continuous monitoring to ensure the safety of user funds and the integrity of the protocol.
