The foundation: blockchain

Cryptocurrencies are based on blockchain technology. The blockchain is essentially a public digital ledger that securely and transparently stores all transactions. Everyone can view the transactions on the blockchain, but the parties involved remain pseudonymous. This transparency builds trust, and the technology ensures that no one can manipulate the blockchain.

Store cryptocurrencies securely

To store your cryptocurrencies securely, you need a wallet, which is a digital wallet. There are two types of wallets: custodial and non-custodial. Custodial wallets are convenient but less secure, as a third party holds your private keys. Non-custodial wallets are more secure, as you control the private keys, but you are fully responsible for securing them.

Cryptocurrencies offer several advantages compared to traditional financial systems. With them, you can quickly and easily send money across borders without relying on intermediaries like banks.

The foundation of cryptocurrencies is the foundational blockchain technology.

Everyone can view the transactions in the blockchain, but the involved parties are pseudonymous. This transparency builds trust and prevents anyone from manipulating the blockchain. In this article, blockchain technology is explained in detail.

Blockchain technology not only impacts cryptocurrencies, but also many other areas. For example, it can help make supply chains more transparent or execute contracts without intermediaries. The possibilities are nearly endless, and blockchain has the potential to revolutionize many industries. Here you can read more about it.

You now know what cryptocurrencies are and how they work. Now let’s look at the different types of assets.

Bitcoin – the pioneer cryptocurrency

Bitcoin is the first and most well-known cryptocurrency. Since its introduction in 2009, it has gained a large following and paved the way for other cryptocurrencies. One of its core features is the limited total supply of Bitcoin. There will never be more than 21 million Bitcoins. This limitation makes Bitcoin scarce and more akin to the concept of gold than a traditional currency. For this reason, Bitcoin is often referred to as "digital gold." Another important aspect of Bitcoin is its decentralization and its independence from governments and banks. This means that no one has control over Bitcoin, just like with gold. Here you can learn more about Bitcoin.

Altcoins – diversity in the cryptocurrency world

In addition to Bitcoin, there are many other cryptocurrencies and projects, known as altcoins. These offer various functions and features. Some focus on transaction speed, scalability, or innovative technologies like self-executing contracts (smart contracts). Well-known altcoins include Ethereum, Ripple, and Dogecoin. In this article, you can learn more about altcoins.

If you want to buy assets, there are several options available. It is important to understand the options in order to make the right decision for you. Below, we will show you what options are available.

Buying cryptocurrencies – getting started

There are different methods to acquire cryptocurrencies. One popular option is to buy through crypto exchanges (Cryptonow Trade®), where you can trade cryptos online. Another option is cryptocurrency ATMs, where you can directly buy and sell cryptocurrencies. Additionally, there are gift cards (Cryptonow Wallet®) that simplify the purchase of cryptocurrencies. Regardless of which method you choose, make sure to inform yourself about the risks and opportunities before investing. Here you can read more about how to buy cryptocurrencies.

After purchasing cryptocurrencies, it is important to store them securely to avoid losses or theft. Below, we will show you the methods for safe storage.

Secure storage of Bitcoin and other cryptocurrencies

To own or trade cryptocurrencies, you need a wallet, which is a digital wallet for cryptocurrencies where you can securely store and send your crypto assets. There are various types of wallets, including custodial and non-custodial wallets. With custodial wallets, a crypto exchange or broker manages your cryptocurrencies. This is convenient, as your coins are always available, but there is a risk that your cryptocurrencies could be targeted by theft more quickly. With non-custodial wallets, you have full control over your cryptocurrencies. You are the “true” owner, and your coins are stored more securely. However, you are also responsible for securely storing your access credentials, as losing them can result in losing access to your coins.

The choice of the right wallet depends on your individual situation. If you trade cryptocurrencies frequently and need regular access to your wallet, an online wallet might be the more suitable option. However, if you own a larger amount of cryptocurrencies and wish to store them securely in the long term, we recommend the safest option, an offline wallet like Cryptonow Wallet®. In this article, the storage methods are explained in more detail.
