    How can I avoid ICO scams?

    In this lesson you will learn how to recognize potential scams in the cryptocurrency sector and what you should look out for.
    The methods of raising funds for new coins are as revolutionary as the blockchain technology itself. ICOs (Initial Coin Offerings) are a breath of fresh air in the fundraising world and may even replace traditional venture capital financing for startups over time.
    However, it also has a few disadvantages. Investing in ICOs is risky. Scams are common and sometimes suspicious schemes are very difficult to spot at first glance.
    Caution: To ensure that you only invest in worthwhile projects, you should be aware of some warning signs that indicate that a project requires a lot of caution.
    Before investing in a project, be sure to ask yourself the following questions:

    Do I understand this plan?

    Does the project have a real “use case” and can I understand it? What is this plan for? Or are only keywords like AI, blockchain, decentralized, revolutionary, etc. used? If a project’s white paper doesn’t make it clear what the project’s goal is and you read on and find yourself more confused than ever, caution is advised. If a project doesn’t make sense to you, you shouldn’t invest in it.

    Can this project have real benefits?

    Can this project be profitable? If not, it will get little attention because people only buy things they value.
    If something looks suspicious to you, it probably is.
    After browsing the website, watching videos about the project and reading the white paper, but still not sure what the project is trying to achieve, you should try the infamous duck test: “If it looks like a duck, swims like a duck and quacks like a duck, then it’s probably a duck.

    Does the ICO project really need blockchain?

    Does this project really need blockchain technology to function or will it work without blockchain? The white paper should clearly explain why blockchain is needed within the project and what role it plays in future product development. You should really only invest in projects that are revolutionary and offer a unique service right after their token ICO.

    Who is behind this project?

    Of course, every now and then, people who appear out of nowhere and have no track record in the industry have brilliant ideas and are busy launching the next big thing on the scale of Google. Unfortunately, however, you’re far more likely to be scammed by actors you didn’t even know existed than by reputable crypto entrepreneurs and developers.
    Ideally, the founders are business oriented and already successful in the industry. For example, they have won awards, they run well-known and established companies, their photos and bios appear in the team section of the website, etc.
    The only exception to this caveat regarding anonymous actors is the Bitcoin Project, created by Satoshi Nakamoto, who still maintains a pseudonym.

    Do your own research.

    If you are interested in a project, you should show your initiative and find out as much detail as possible. Read white papers and posts on social media like Medium, Telegram and Discord, interact with others and find out everything you want to know. However, never base your decisions on someone’s internet posts, such as forums.

    Do a project’s “bad times” show up in the roadmap?

    Every serious project should present a clearly structured plan that is always up-to-date and includes all project phases, old and new goals and milestones. If the project plan is incomplete or unstructured, something is wrong. Remember: No matter what project you are interested in, if there is no roadmap available, you should reconsider your investment. Don’t forget to do your research.

    Can you chat with the founders?

    We can all imagine how busy the schedule of project initiators must be. Those who approach a project with passion still make sure to allow enough time to interact with their community and not disrupt the flow of information. It is ideal if the founders of a project are reached through Telegram or other social channels and regularly informed about the project.
    It shows professionalism when project managers keep their community informed about the current status of the project and any changes. This means that they value the opinion of their community. If project managers are keeping a low profile or are unwilling to comment, there may be a reason.
    • Attention: If a project meets all the requirements, it is not guaranteed to succeed.
    People who do not make hasty investment decisions and invest carefully will learn to recognize how an ICO was created for purely fraudulent purposes. If you spot a scam early, you can invest in an ICO instead, which will pay you back in both time and money.

  • Can cryptocurrencies like Bitcoin be hacked or blocked?

    Can cryptocurrencies like Bitcoin be hacked or blocked?

    Bitcoin is considered hack-proof because the Bitcoin blockchain is constantly verified by the entire network. Therefore, threads on the blockchain itself are very unlikely.

    • Since blockchain technology is centralized and distributed, hacker attacks can be safely prevented.
    • A 51% attack can unbalance the blockchain.
    • Bitcoin has never been hacked until now.
    • Wallets used to store cryptocurrencies are easier to hack than blockchains.
    • Accordingly, there are always successful hacker attacks on people and websites.

    Why Bitcoin Can Be Considered “Hack Proof”?

    Bitcoin is considered hack-proof because the Bitcoin blockchain is constantly verified by the entire network. Therefore, attacks on the blockchain itself are very unlikely. To add a new block with bundled transactions, each participant (miner) solves complex mathematical problems by constantly updating the Bitcoin database.
    These complex mathematical problems arise from Bitcoin’s cryptographic hash function. When a particular block is added to the database, every node in the network must agree on the block’s validity. Only when all nodes match will the Bitcoin database be updated accordingly.
    Manipulation of the cryptocurrency network is almost impossible. Decentralized, temporal, computational and powerful Bitcoin blockchain not only prevents deletion and overwriting of pre-validated Bitcoin block, but also prevents double spending.

    What happens if a hacker attacks the Bitcoin blockchain?

    As you already know, there is not just one copy of the Bitcoin blockchain. Instead, every node in the Bitcoin network has a copy. Nodes are distributed worldwide and contain all Bitcoin transactions made to date.
    A hacker who wants to change the distributed database of Bitcoin or any other network based on blockchain technology will have to hack not one, but more than half of the computers participating in the network (51% of the attack).

    What is a 51% attack?

    A 51% attack is the biggest threat to the blockchain if such an attack is successfully carried out by a person or organization and thus captures most of the network’s mining power (hashrate) and compromises Bitcoin’s transaction history. can go. The network can be changed and overwritten purely theoretically.
    A majority (i.e. 51%) is always required to decide which transactions are accepted and which are rejected. This means that a majority of 51% can change the blockchain’s distributed database. This will cost twice as much – it is possible to spend the same transaction multiple times. However, it is very rare that such a scenario will actually occur.
    A 51% attack on Bitcoin has never succeeded, and the network has never shut down, even for a brief moment.

    Can Bitcoin be locked/unlocked?

    A 51% attack on Bitcoin has never succeeded, and the network has never shut down, even for a brief moment. Additionally, several authorities and banks have repeatedly called for the shutdown of the Bitcoin network. Every time without success, because Bitcoin has been running without interruption for almost 10 years.
    For a complete system failure of the Bitcoin network, many things would have to go wrong. Here are a few “doomsday scenarios”:
    If there was a worldwide power outage, the Internet and all communication channels were shut down, the nodes in the network would not be able to communicate with each other and the entire Bitcoin network would shut down.
    The Bitcoin update contains a malicious bug that was not detected in the Bitcoin protocol despite careful testing and review of the peer-to-peer network. The network will likely crash for a short period of time. This could lead to a drastic drop in the price of Bitcoin and a fork of the blockchain.
    Bitcoin is decentralized and therefore theoretically cannot be banned by any single government. However, there have been attempts in the past to ban cryptocurrencies or limit their use. Since one government cannot do much on its own, several governments can work together to push for a ban on cryptocurrencies. However, it is highly likely that governments will pass laws to protect investors and tax laws.
    A 51% attack represents an unexpected but serious threat, however, for such an attack to be successful, not only 51% of network participants would be required, but also a huge investment in mining equipment. It will be necessary. In addition to these factors, it is highly unlikely that such a majority will occur, as network participants will also risk their profits.
    Additionally, new and supposedly better cryptocurrencies are introduced to the markets almost daily. Such developments risk market fatigue when it comes to investing. This means that once all the investors

    Why are bitcoins stolen?

    Most cryptocurrency thefts involve users and websites that do not take proper precautions when storing them. Often, coins that are kept in places where they are not safe are stolen.
    For example, a “hot wallet” is any cryptocurrency wallet that is connected to the Internet or “online” in some way. Hot wallets are wallets on desktop or mobile devices, as well as wallets hosted by an exchange that has failed to keep its security measures up to date. A hot wallet can also refer to wallet private keys that are carelessly stored on a compromised, hackable device.
    Cryptocurrencies are stolen because they are stored in unsecured locations.
    The Mt.Gox hack is perhaps the biggest example of poor security precautions and the biggest theft of cryptocurrencies. Mt Gox was an exchange founded in Japan and converted to a Bitcoin exchange in 2010. Due to lack of security measures, more than 850,000 BTC were stolen. Mt. Gox hack is the biggest hack since the creation of Bitcoin and led to the bankruptcy of the exchange in 2014.
    Fortunately, other exchanges around the world learned from this incident and have since kept their security measures up to date. However, we recommend that all cryptocurrency users practice prudent security habits and read our article on how to store cryptocurrencies safely.
    Although certain security precautions must be taken, blockchain technology with its distributed database is one of the most innovative and important innovations to date. Blockchain technology opens the door to many applications that are just waiting to conquer the world.
