Blockchain is a decentralized and immutable digital ledger technology. A blockchain consists of a chain of blocks, each containing a secure record of transactions. Blockchain technology ensures transparency, security, and eliminates the need for intermediaries in various industries like finance, supply chain, and more.

Here is an example of how blockchain technology works. Imagine a digital notebook that many people can write in and see, but no one can change what’s already written. This notebook keeps a record of transactions like who gave what to whom. These transactions are put together in blocks, and each block is connected to the previous one, forming a chain. This helps keep everything transparent and secure, making it useful for things like money or tracking items in a big store.

Proof of work (PoW) is a security method used in blockchain systems. Proof of work is the original consensus mechanism that requires participants, called miners, to solve complex mathematical puzzles to validate and add new transactions to the blockchain.

This validation process ensures that the transactions are legitimate and helps maintain the integrity of the decentralized network by making it computationally expensive to alter past transactions. Proof of work was designed to prevent double spending, a major issue in cryptocurrency.

In simple terms, proof of stake (PoS) is another way to secure a blockchain network.


What is the difference between proof of work and proof of stake?

Instead of solving puzzles like in proof of work, participants, known as validators, are chosen to create new blocks and validate transactions based on the amount of cryptocurrency they hold and are willing to “stake” as collateral.

The proof of stake method aims to reduce energy consumption compared to proof of work and encourages validators to act honestly to avoid losing their staked funds.

A smart contract is like a digital agreement that automatically executes actions when certain conditions are met. A smart contract is written in code and runs on a blockchain, so it’s secure and can’t be changed once set up. This provides transparency for all parties involved.

The goal of a smart contract is to eliminate the need for intermediaries in various situations, ensuring that actions are taken exactly as agreed upon.

Examples of uses for smart contracts:
• Facilitating crowdfunding
• Insurance agreements
• Simplifying real estate transactions

A cryptocurrency wallet is like a digital wallet for your digital money. It’s a secure place where you can store, send, and receive cryptocurrencies like Bitcoin or Ethereum.

Just like a physical wallet holds your cash and cards, a cryptocurrency wallet holds your virtual coins and keeps them safe. Cryptocurrency wallets make it easy to send and receive digital assets.

There are several types of cryptocurrency wallets, each with its own features and security. You can learn more about these different types of wallets in our cryptocurrency courses.

Cryptocurrency coins are standalone digital currencies that operate on their own blockchains, such as for example Bitcoin or Ripple’s XRP. Cryptocurrency coins have their own unique networks and use cases.

Tokens are digital assets that are built on existing blockchains, such as Ethereum. Tokens represent assets, contracts, or access rights within a specific ecosystem. Tokens can be used for example for decentralized finance (DeFi) applications or digital collectibles.

Cryptocurrency staking is when you hold and “lock up” a certain amount of a specific cryptocurrency in a wallet to support the operations of a blockchain network. In exchange, you earn rewards or interest, usually in the form of more of that cryptocurrency. Staking helps keep the network secure and validate transactions, providing an alternative to traditional proof of work mining.

Decentralized finance, or DeFi, is a financial system built on blockchain technology. DeFi is like traditional finance, but decentralized and open to everyone. With Decentralized Finance, you can do things like lending, borrowing, trading, and earning interest without needing banks or other middlemen. DeFi applications use smart contracts to automate and streamline these processes, making finance more accessible and transparent.

Dollar cost averaging is a simple investment strategy. You regularly invest a fixed amount of money into an asset, such as stocks or cryptocurrencies, no matter what the current price is. Dollar cost averaging helps balance out the impact of market volatility over time, because you buy more when prices are low and less when prices are high. It’s a smart way to potentially lower the risk of making bad timing decisions in the market.

Here are 10 common crypto mistakes to avoid:

  1. Lack of Research and Knowledge:
    Don’t invest until you know what you are getting into. Before investing, take time to understand the projects, technologies, and teams behind cryptocurrencies.

  2. FOMO (Fear of Missing Out):
    A lot of beginner crypto investors are buying in during hype, hoping to turn their investment into huge returns. Avoid buying into hype without careful consideration, as it can lead to potential significant losses when prices fall.

  3. Ignoring Security:
    Don’t neglect to secure your cryptocurrency holdings. Protect your cryptocurrency holdings with strong passwords, two-factor authentication, and hardware wallets.

  4. Overtrading:
    Don’t make too many trades based on emotions or short-term fluctuations, as this can result in unnecessary fees and losses.

  5. Ignoring Regulation:
    Stay updated on legal and tax regulations related to cryptocurrency transactions in your country.

  6. Chasing Hyped Projects:
    Evaluate fundamentals rather than investing solely based on hype or social media trends.

  7. Leverage and Margin Trading:
    Understand the risks before using leverage, as it can lead to significant losses.

  8. Investing More Than You Can Afford to Lose:
    Only invest what you can afford to lose, as cryptocurrencies can be highly volatile.

  9. Falling for Scams:
    Be cautious of fake ICOs, fraudulent projects, or Ponzi schemes promising unrealistic returns.

  10. Not Backing Up Wallets:
    Always back up private keys or recovery phrases to prevent losing access to your cryptocurrency holdings.


Avoiding these common mistakes is crucial for beginner crypto investors to navigate the volatile cryptocurrency market successfully. If you’re eager to delve deeper into crypto, consider exploring our courses.

Fiat currencies, backed only by the trust of the issuing government, have a long and storied history marked by both successes and failures. Fiat currencies are not immune to failure and by examining past instances of fiat currency collapses, we can glean valuable insights into the risks and repercussions associated with such failures.


Understanding Fiat Currency Failures

  • Fiat currency derives its value from government decree rather than being backed by a physical commodity like gold or silver.
  • When confidence in the issuing government erodes, fiat currencies can experience rapid devaluation or even total collapse.


Consequences of Fiat Currency Failures

  • Economic instability: Fiat currency failures often lead to economic turmoil, including hyperinflation, unemployment, and diminished purchasing power.
  • Social unrest: Severe currency devaluation can erode public trust in the government, leading to civil unrest and political upheaval.
  • Loss of savings: Individuals holding fiat currency savings may see their wealth evaporate overnight as the value of the currency plummets.


Why Fiat Currency Fails

  • Mismanagement by central banks: Poor monetary policy decisions, such as excessive money printing, can erode the value of fiat currencies over time.
  • Loss of confidence: Fiat currencies depend on public trust and confidence in the issuing government. Once trust is lost, currency devaluation can spiral out of control.


The historical lessons of fiat currency failures serve as a stark reminder of the inherent risks associated with relying solely on government-backed money. From hyperinflationary disasters to widespread economic collapse, the consequences of fiat currency failures are profound and far-reaching.

What Is A Rug Pull?

Rug pulls are malicious scams where the project’s creators use slanderous marketing techniques and project positioning. By doing so, they get investors to invest in their project and later abandon ship, leaving the investors rekt.

The developers usually pump up hype around the project and artificially inflate the value of the token by riding on pop culture trends (Squid Game token) and by extensive shilling. This often lures newbie investors to purchase them and inject liquidity into the project’s pool.

At this juncture, the developers “pull the rug” by withdrawing the capital locked in the liquidity pool or halt users from withdrawing funds and closing down all social media handles and communication forums. This causes the price of the token to drop rapidly and investors lose their invested capital in the project.

How To Know If A Coin Is A Rug Pull?

So, with all the noise on social media, how can you, as a new investor, be smart enough to avoid these cash grabs?

Below are a few red flags that you could watch out for when you do your research on a cryptocurrency or an NFT project.

Project Creators Seem Shady

If little to no information regarding the token’s origins or founders, or team is accessible, this might be a potential cause for concern of a potential rug pull.

Many blockchain projects have un-doxed teams. But that does not mean that it is a scam. BAYC, Soul Dogs City, Bitcoin, and Monero are examples of good projects with anonymous teams.

Nevertheless, scammers are extra careful to not reveal their identities. So, if it’s your first time or you choose to invest an uncomfortable amount of money in a project, it is best to know the team.

Make sure that the project creators do not have a history of scams or illicit activities.

Further, you must examine how the distribution of the circulating supply of the token across wallets. If only a few wallets hold a majority of the coins, it’s possibly a red flag. The fact that a few wallets own a large share of the token supply suggests that they can very well manipulate the coin’s value.

“Whatever the reverse in this space of a rug pull is, is exactly how I went into it.”

— Gary Vaynerchuck, 2021

No Locked Liquidity 

To inspire confidence in crypto investors, developers of ventures typically restrain holding authority over the liquidity pool. This is known as locked liquidity, because it prevents developers from transacting any of the pool’s tokens, making token theft or substantially lowering liquidity extremely difficult.

The longer the pool is sealed, the more trustworthy it is and lowers the chance of a rug pull. If the liquidity, on the other hand, is not locked, nothing prevents the developers from withdrawing it and making a run for it.

Inactive or Shilling Community

Rug pull projects tend to have a high social media following but poor engagement.

Some rug pull projects rely on social media influences, crypto influencers, and paid advertisements to garner support for the project. For instance, the Squiggles rug pull involved the project supposedly holding the support of 232,000 Twitter users and 360,000 members in discord.

This points out clearly the fact that the project is trying to fake user engagement on their forum and project to investors that they have a strong community.

Skyrocketing Prices and Short-term High Yields

Many DeFi pools offer to ease token trades and claim to generate additional returns for pool investors. WhaleFarm, for example, had an APY of over 100%. If a yield farm appears to be giving profits that are too good to be true, they most likely are.

Scammers of rug pull projects might inflate a project by investing money into it or shilling excessively to get others to participate out of FOMO.

Always DYOR on news about the venture including new exchange listings, partnership announcements, or other related news. It might be a rug pull or a pump-and-dump scheme if these aren’t present. Unless you have a compelling reason to be otherwise, be wary.

A cryptocurrency airdrop is a distribution of free tokens or coins to holders of a particular cryptocurrency or users of a specific platform. Airdrops can be done as a promotional strategy by crypto projects to gain attention and adoption, or as a reward for loyal community members. Airdrops often involve sending a certain amount of the new tokens to eligible participants’ wallets, increasing their involvement in the project’s ecosystem.

A DAO, or Decentralized Autonomous Organization, is a type of organization that operates based on rules defined by code and executed on a blockchain. A DAO aims to achieve decision-making and governance through a decentralized process, where participants holding the organization’s tokens can vote on proposals and changes. The concept of Decentralized Autonomous Organisations eliminates the need for centralized authorities and enables community-driven management of projects, funds, and protocols in a transparent and open manner.

A soft fork maintains compatibility with older nodes, while a hard fork introduces changes that are not backward-compatible and can lead to a split in the blockchain’s history.

What is a Soft Fork?

A soft fork is a backward-compatible upgrade to the blockchain protocol. It involves tightening or restricting the rules of the network. Nodes that haven’t upgraded can still operate on the network, but they might not be able to participate in new features or transactions.

What is a Hard Fork?

A hard fork is a more significant and potentially disruptive change to the blockchain protocol. A hard fork introduces new rules that are incompatible with the old ones, leading to a split in the blockchain. This can result in two separate chains and requires all participants to upgrade to the new rules to remain on the same network.

In simple terms, an NFT is an asset that has been tokenized via the blockchain.

NFT stands for Non-Fungible Token and it is a unique digital asset that represents ownership or proof of authenticity of a specific item or piece of content, such as artwork, collectibles, music, videos, and more, using blockchain technology.

Unlike cryptocurrencies like Bitcoin or Ethereum, which are fungible and interchangeable, NFTs are distinct and cannot be exchanged on a one-to-one basis. Each NFT has a verifiable and unchangeable record on the blockchain, making it valuable for digital ownership and provenance in the digital world.
