Will you let them do it? The digital world is developing at an incredible pace, changing every year and providing us with an amazing range of possibilities that were not available to us until recently. Along with it, the world of threats is also evolving rapidly, and in the concern for our funds and personal data, we must effectively combat them. Right now, you have two options before you: take advantage of this course offering and learn important safety principles, acquiring specific habits that will allow you to safely enjoy all the benefits of the internet, such as using Metaverse, digital reality, cryptocurrencies, blockchain, and web3 applications. Alternatively, the second option is to remember this course when it's already too late, and your wallet is emptied, cryptocurrencies disappear, or you lose access to your funds.

We will examine security aspects related to the use of dex and cex exchanges, as well as decentralized applications, focusing on passwords, seed phrases, two-factor authentication, backups, and external wallets. There will also be knowledge about antivirus software, VPN, and several other essential topics. And all of this is arranged in a logical way, explained in simple language, as if everyone could fully understand everything.

  • Scams and external threats (part 1)13:07

    What is a scam, exactly? In other words, it is a fraud resulting in the intentional actions of individuals or third parties causing us to lose money or exposing our sensitive personal data, putting us at real risks in the future. To be completely honest, scam is a topic that cannot be fully covered because cryptocurrency market deception evolves rapidly, changes extremely quickly, and hackers constantly come up with new, creatively cunning ideas to try to access our wallets. This is the first crucial piece of information you should remember. Despite everything you will hear in this material, you should never be convinced that you know it all because there is always the possibility of something new emerging that will completely catch you off guard. In the later part of this course, I will share with you the principles I have been successfully using for many years to be prepared even for potential threats that we may not be aware of today. Most of the online security content revolves around issues such as downloading malicious software, entering your password in the wrong place, clicking on a malicious link, granting access to your wallet to unwanted applications, and so on. In this material, I will show you the most important examples of the most dangerous scams, with many of which I have personally encountered and those that occurred during my presence in the market, allowing me to directly and continuously monitor each of them, gaining valuable experience. If you are dealing with a capital of a few dollars, this material will be an interesting addition and knowledge that may simply come in handy someday. If your portfolio is in the hundreds or thousands of dollars, please keep in mind that it is always worth taking a moment to reflect on what and how we are doing, so that, due to haste or lack of knowledge, we don't end up doing something foolish. I assume that valuable lessons will be better for you than costly ones. This material aims to show you a certain skepticism because often it is precisely a skeptical approach and composure that will save your own back. In this material, you will learn how pyramid schemes, also known as Ponzi schemes, operate, what Raq Pool is, and how it functions. Additionally, you'll delve into everything related to phishing firsthand, based on experiences with Ledger and Trezor, along with numerous examples. Let's get started!

  • Scams and external threats (part 2)14:13

    This recording is a continuation of the material on external threats that we may encounter while navigating the world of cryptocurrencies. In this part, we will examine counterfeit applications and wallets, impersonation of government institutions, police, and the tax office, sponsored advertisements, Telegram, Instagram, platform X, and other messengers, as well as social media, including posing as support staff and impersonating well-known individuals. In addition to these topics, you will learn some facts about dishonest exchanges that deceive people, fake airdrops of both tokens and NFTs leading to capital loss, but most importantly, for each of these situations, I will discuss practical principles of conduct to secure yourself against them and avoid any unnecessary risks. Are you ready for a series of interesting examples based on real stories that actually happened? Let's see if you can survive!

  • Costly mistakes, and internal threats11:46

    Routine, lack of knowledge, haste, or lack of attention can result in a single click depriving us of a lot of money and destroying the effects of all our investments, even those very well thought out. Learn the details of behaviors and actions over which only we have control, but which, due to our mistakes, can be particularly dangerous. In this material, I discuss all the situations in which, for various reasons, we can harm ourselves, so it's worth knowing and being aware of what to do and what not to do to avoid regrets. From trivial matters to truly advanced issues, everything is prepared in an absolutely concentrated form especially for you, so let's get to work!

  • What factors affect our portfolio and what situations should we be mindful of35:20

    Can changes in cryptocurrency prices be predicted? What factors influence the color of market bars? Are there methods to increase your chances of success? Does technical analysis work? What situations cause declines, and which ones lead to increases? What do Celestia (TIA) and Dymension (DYM) have to do with this topic? Discover the answers to all these questions in this material!

  • How not to lose everything - success investor's mindset31:54

    In this material, you will discover why only a small percentage of people consistently earn on the cryptocurrency market. You will learn how an effective investor thinks and operates, what they avoid, and the unbreakable principles they adhere to. This content is one of the most valuable insights presented throughout this training. I've dedicated nearly 7 years and significant amounts of money to gain the experience and skills that I can now share. Each year and each month, based on profits and losses, mistakes, problems, and successes, I've kept meticulous notes, which I've thoroughly analyzed and compiled to create the material titled "Why 98% of people lose in the crypto market." Seize this information and leverage it to join the 2% of successful individuals.

  • Safe handling of dApps, web wallets, and DEX exchanges8:58

    The world of decentralized finance and applications differs from the classic centralized exchange used in everyday life. It requires greater knowledge, the use of web3 wallets, understanding of cross-chain transfer rules, awareness of gas fees for transactions, and many other additional elements that together influence the quality of what we do. In this material, I will address the most important elements related to the DeFi world and show you what I pay attention to when conducting all my operations. I clearly remember that my beginnings were quite complicated, and elements that once caused me problems at the beginning still make life difficult for novice investors. Enjoy the session!

  • Safety habits on CEX exchanges5:18

    There are a few simple rules to follow that will make our lives easier and reduce the chances of potential loss due to mistakes or lack of knowledge in the crypto world. Centralized exchanges are private companies, so I consistently advocate for adopting a very specific approach when using their services. Learn the details by watching this video.

  • How not to lose everything - principles worth following7:03

    In this material, I have included information that was not covered in the previous recordings or was only briefly mentioned. Routine, haste, and carelessness are our main adversaries in controlling our cryptocurrency finances. A collection of the most important principles to keep in mind, including the most popular elements that deserve special attention, can be found in this video.

  • Key elements - seed phrase, 2FA, passwords, and backups8:41

    The seed phrase, backups, and two-factor authentication (2FA) are three key elements we need to take care of to fully ensure all possible security solutions. The world is divided into two groups: people who make backups and those who haven't made them yet. I myself was once in the latter group, which led to a rather costly loss that taught me how to proceed correctly. Today, I would like to share this experience with you!

  • What is diversification and how does it work5:25

    Diversification is one of the best methods to reduce potential investment risks, regardless of what we invest in. Learn about diversification in the case of cryptocurrencies and beyond. Is investing everything in one project a good idea, and what are the exceptions to this? Discover an approach that will help you minimize potential losses and reduce the chances of wiping out your account through a wise and prudent approach.

  • Can AI be dangerous?8:21

    Is AI dangerous? In this video, we explore the growing concerns around artificial intelligence. From a robot attack at a tech festival in China to Facebook AI developing its own mysterious language, the advancement of AI raises serious questions. We also dive into the integration of AI and blockchain, and what the future might hold if machines become smarter than us. Is this innovation or a potential threat to humanity? Join us as we uncover the facts, real events, and chilling possibilities behind AI development.
