A beginner's guide to buying your first cryptocurrency

More than a decade has passed since the first digital coin, Bitcoin, was launched, and cryptocurrencies continue to be a hot buzzword and asset in the digital economy. Their continuous growth in both numbers and value prove to critics that they are not a fad. Instead, they hold various benefits in several ways, such as empowering you to be your own bank by buying goods and services, as well as trading them for profit. 

Crypto is undoubtedly an exciting industry filled with many possibilities. Yet at the same time, understanding its blockchain technology and exploring over 6,000 digital coins circulating the market can be confusing. Thankfully, the first step to entering their world is buying digital currencies that can be done in a few following easy steps presented on this page. 

  1. Get a wallet and choose your preferred storage method

Similar to fiat money, you first need to have a wallet to store your crypto. The difference, however, is that it is digital that varies into two major different types: hot and cold crypto wallets. They are also called online and offline storage, respectively. Meaning, the former is connected to the internet, whereas the latter is not and instead uses portable devices like a flash drive. With each having respective pros and cons, Bitcasino lists down their two or more subtypes to help you decide even better. 

Hot wallet

Hot wallets are hassle-free and convenient, perfect for everyday use and basic transactions. That said, while their connection to the internet allows you to access your account wherever you are and whenever you want, it also means that you are vulnerable to digital dangers like technical errors and mischiefs. As such, you need commendable hot wallets to prevent such problems, but first, take a look further below for their subtypes. 

  1. Mobile wallet — Since many people are with their mobile devices at all times, this software is perhaps the most ideal for daily transactions. 
  1. Web wallet — If, however, you don’t like to download apps, web wallets are another great option because they connect you to the network through a browser interface. 
  1. Desktop wallet — This option is, by far, the safest hot wallet because you need to download it on your personal computer, thus giving you full control and access to your storage. However, it is also highly suggested that you create its backup as a precaution. 

Cold wallet

As mentioned above, cold wallets are portable devices that only become online when used for transactions. Their secure offline storage feature makes them ideal for business owners, long-term crypto traders, or as what the industry likes to call them, hodlers (users who ‘hold on for dear life’). Here are their two subtypes:

  1. Hardware wallet — This electronic device (i.e. flash drive) uses a random number generator (RNG) in producing public and private keys. 
  1. Paper wallet — This is a piece of printed paper that includes a crypto address and its keys through QR codes. 
  2. Find a reliable crypto exchange

Once done sifting through the many, many hot and cold wallets available in the market, another platform you need to meticulously find is a crypto exchange. It is a digital marketplace where owners can buy and sell digital currencies, and even convert fiat money into other assets according to the market value.

While crypto exchanges are like traditional stock exchanges — market makers that take bid-ask spreads as their extra charges for every transaction — they vary into three kinds. These are centralised (CEX), decentralised (DEX), and hybrids, each of which holds significant pros and cons depending on your preferred services. 

  • CEX — Directly controlled by a central organisation, CEX manages your transfer funds and wallets. It normally has higher liquidities and a more stable market than DEX. 
  • DEX — Thanks to smart contracts, this exchange depends on an automated process in controlling your assets. As a result, its low liquidity creates a more volatile market. 
  • Hybrids — Unlike crypto wallets where you can only choose between two types, there are a few exchanges that combine CEX’s low latency and fast transaction speeds and DEX’s smart contracts. Hybrids are the ideal solution for preventing yourself from the market’s volatile risks. 

To further protect yourself from several digital dangers, you need to rely on platforms that have the six following essential qualities: 

  • Legality
  • Trustworthy
  • Security
  • Used technology
  • User experience
  • Liquidity
  1. Create and verify your account

Licensed crypto wallets and exchanges have successfully met federal regulatory requirements, including KYC (know your customer). Otherwise known as ‘know your client’, it is the process of verifying your identity by either submitting a copy of your passport/driver’s license or uploading a selfie to further prove your appearance matches your documents. 

  1. Deposit cash to your account

Before buying any crypto, you must first ensure that you have funds in your account. As said before, many exchanges allow users to convert fiat money into their preferred coins. Now, how it is done varies from one marketplace to another, possibly ranging from linking a bank account, authorising a wire transfer, or settling payment with a debit/credit card.   

  1. Place your crypto order

Now that the money is available in your account, you are ready to finally place your crypto order. The problem, however, is that there are more than 6,000 digital currencies circulating today in the market. 

To get you started, listed as follows are the top 10 digital currencies in October 2021 based on market cap. 

  1. Bitcoin (BTC): Over $821 billion
  2. Ethereum (ETH): Over $353 billion
  3. Tether (USDT): Over $68 billion
  4. Cardano (ADA): Over $67 billion
  5. Binance Coin (BNB): Over $64 billion
  6. Ripple (XRP): Over $44 billion
  7. Solana (SOL): Over $41 billion
  8. USD Coin (USDC): Over $31 billion
  9. Polkadot (DOT): Over $28 billion
  10. Dogecoin (DOGE): Over $26 billion

Key Crypto Terms Every Beginner Needs to Know

Before diving into your first trade or transfer, it's essential to get a grip on the lingo of the crypto world. Familiarizing yourself with these key terms will enhance your interactions with digital assets and boost your confidence as you explore various tools, communities, and platforms.

Wallet

Think of a wallet as your digital vault for cryptocurrencies. It can come in two forms: software-based (like online or mobile apps) or hardware-based (physical devices that keep your private keys safe offline). Remember, wallets don't actually hold the coins; they store the pairs of keys that give you control over those coins on the blockchain.

Transaction

In the crypto realm, a transaction is all about moving assets from one address to another on a blockchain network. Every single transaction is recorded publicly and permanently on the blockchain, capturing details like the amount, timestamp, sender and recipient addresses, and a unique transaction ID.

Blockchain

The blockchain is a decentralized, distributed ledger that keeps track of all transactions across a network. Each block in the chain contains a list of transactions and is cryptographically linked to the one before it, creating a secure chain. For example, Bitcoin's blockchain adds a new block approximately every 10 minutes, verifying and recording the latest transactions.

Tokenomics

Tokenomics is a blend of "token" and "economics." It explains how a crypto asset is structured and how it behaves economically, covering aspects like supply mechanisms, distribution models, incentives, and use cases. Take Bitcoin, for instance; it has a capped supply of 21 million coins, which introduces a built-in scarcity that influences its value over time.

Public and Private Keys

A public key acts like an address-you can share it to receive crypto. On the other hand, a private key is your secret digital signature that you use to sign transactions and access your assets. If you lose your private key, you lose access to your crypto, as no one else can retrieve or replace it. These keys are typically stored in your wallet.

Gas Fees

Gas fees are the costs that users pay to get their transactions processed and validated on a blockchain network. Take Ethereum, for example; here, gas is measured in "gwei," and the price can fluctuate based on how busy the network is. More complicated transactions, like minting NFTs or engaging with smart contracts, usually come with higher gas fees.

Asset Volatility

Volatility is all about how quickly the price of a crypto asset can change. Cryptocurrencies are known for their wild price swings compared to traditional assets. For instance, Bitcoin experienced daily price fluctuations of over 5% more than a third of the time in 2022, according to Coin Metrics. This kind of volatility brings both opportunities and risks, shaping the strategies that traders and investors use.

Now that you've got this terminology down, diving into whitepapers or exploring exchange platforms should feel a lot easier. Take a moment-how many of these terms clicked for you right away? The more comfortable you get with this language, the easier it will be to navigate the world of crypto.

The last words: Dos and don’ts in the crypto market

Before we let you go and explore more of the crypto market, Bitcasino leaves you 10 important tips to remember:

  1. Don’t invest more than you can afford to lose.
  2. Research thoroughly.
  3. Beware of platforms or features that sound too good to be true.
  4. Don’t join new trends simply because you have FOMO (fear of missing out).
  5. Religiously verify whatever offers you find online.
  6. Beware of ‘unit bias’.
  7. If they are not your keys, then they are not your coins.
  8. You can buy a fraction of a bitcoin (not the whole lot).
  9. Try to explore more other digital currencies. 
  10. Study the changing crypto-related regional laws (i.e. legality and tax consequences).

Cracking the Code: How Blockchain Powers the Crypto Universe

Blockchain: The Foundation of Every Cryptocurrency

Every cryptocurrency transaction is built on a blockchain. This technology acts like a distributed digital ledger, keeping track of each transaction across a network of computers. Instead of relying on a single database controlled by one organization, blockchains share data among participants, known as nodes, who work together to maintain a synchronized and transparent record of every event.

Information on the blockchain is organized into blocks, which are linked together in chronological order, forming a continuous chain. Each block holds a collection of transactions, a timestamp, and a cryptographic reference to the previous block. Once a block is added to the chain, its contents can't be changed without the consensus of the majority of the network-making it nearly impossible to manipulate.

Decentralization and Consensus Take the Place of Central Authorities

In traditional systems, we often depend on banks or payment processors to verify and approve transactions. But with blockchain, that middleman is eliminated. Instead, transactions are confirmed through consensus mechanisms, with two of the most popular being:

  • Proof of Work (PoW): This method, used by Bitcoin, requires miners to tackle complex mathematical puzzles. The first one to crack it gets to add the block to the chain and earns a reward.
  • Proof of Stake (PoS): In networks like Ethereum 2.0, validators are selected based on how much cryptocurrency they "stake." The more coins you stake, the better your chances of validating the next block.

These consensus methods empower decentralized networks to agree on the legitimacy of new transactions without needing a central authority. No single person can dictate what gets added; instead, decisions are made collectively, resulting in a shared record that's both transparent and resistant to tampering.

Trust is Built on Transparency and Immutability

Blockchains establish a permanent record. Anyone can look up the history of a public blockchain like Bitcoin or Ethereum, and once a block is confirmed, it can't be deleted or altered. This immutability fosters trust. Data isn't safeguarded by secrecy but by openness and cryptographic security.

Trust doesn't stem from who runs the system, but from how it operates. Curious if a Bitcoin payment actually went through? You don't need a bank statement for that. Just check the blockchain. This ability to independently verify transactions is changing the way people exchange value, enforce contracts, and prove ownership in our digital age.
