Cryptocurrencies’ anatomy: How to Make Money from Them 541

Today as cryptocurrency rates continue to increase, many potential investors go all-in on digital assets. However, they do not actually consider their nature. The Coin Shark will try to explain these complex issues, make it clear what cryptocurrency is and how you can make money out of it.

History

Back in 1992 former Intel employee Timothy May suggested the idea of a virtual currency that will serve as an anonymous payment tool and will enable people to make financial operations without state control. A bit later, in 1998, another group of enthusiasts proposed to create a chargeless and tax-free monetary system. However all these issues remained unsolved until an unknown stranger called Satoshi Nakamoto suggested the concept of Bitcoin in 2008. He decided to build a chain of information about transactions.

What is cryptocurrency?

This is actually electronic money or digital assets that are created by private computer systems using particular cryptoalgorithms. State authorities and banks can not control such systems.

Such a system has no single secure nod which actions are guaranteed or which can confirm accuracy of other operations. The technology of building a chain of transaction blocks (blockchain) is used in order to solve this problem. Blockchain is the basis for Bitcoin and some other cryptocurrencies’ operation. Separate boxes with stored data are called blocks. All the blocks are connected. So, there is a chain of blocks which explains the name Blockchain. The connection is made by recording a hash-sum of the previous block in new blocks. It is almost impossible to change a separate block because then you will have to hack every block in the chain.

Every participant has their own private (closed) key and a public (open) key. The private key is used for signing a “letter for transfer of property”. This key is the cornerstone of every transaction and it guarantees transaction of cryptocurrency from one participant to the other. The public key is used for confirming blockchain transactions of other participants.

How are transactions made?

Special users (miners) help providing transactions. They receive random transactions and distribute them in the chain. After the transaction was confirmed by a miner, every node should add it to its database. Miners are rewarded with Bitcoin or other virtual currency for providing the system with the capacity of their computers.   

How to make money from cryptocurrency?

There are several main ways of making money from cryptocurrency: mining, investments, trade.

Mining is a process of gaining coins for solving the chain of hash blocks. Miners’ capacity or capacity of a computer are used for the process of decryption. Either personal computer or special mining equipment can be used for this.

In order to invest in cryptocurrency, first of all, you should buy it at an exchange and then wait until its rate grows. In this case the most beneficial currencies are developing currencies because their growth is the most rapid. However the risks are also higher.   

The Coin Shark has already published an article about promising cryptocurrencies that can be worth your attention. Besides, we have already given the instructions on how to choose a cryptocurrency exchange.

The other strategy is to invest in popular cryptocurrencies when their rate fall. They have high volatility and can rapidly restore the previous rate.

Blockchain Transactions: How Do They Work and How to Track Them? 162

blockchain transactions

Satoshi Nakamoto, the creator of Bitcoin, published an article “Bitcoin: A Peer-to-Peer Electronic Cash System” in 2008 and introduced a fundamentally new way of exchanging money. From that moment on, the need for a third party, like a bank or other financial institution, simply disappeared. In fact, this has become a new financial revolution.

Today we will talk how blockchain transactions are conducted from a technical point of view, how reliable they are, what features they have and how they can be tracked.

1. How does blockchain work in general?

We should start with the fact that Bitcoin is the first ever completely digital currency. Unlike electronic money, it does not exist even as a digital file. It is a huge stream of data about all the transactions that have ever been conducted. Blockchain is presented in the form of a giant accounting book, which is available to all network participants.

Each transaction is not stored separately, the information is placed in the blocks. Different networks have different block sizes, for example, until recently one block in the network of Bitcoin “weighed” 1 MB. But the BitMEX report says that after the introduction of the new SegWit protocol, the average size of one block has increased to 1.06 MB, and some have reached 2 MB.

In order to obtain a new block, there are different mechanisms for consensus. The most widespread ones are:

  • PoW (proof of work). Here, the miners need to solve a complex cryptographic equation. After that, a new block is added, for which the system rewards the finder with a certain number of coins.
  • PoS (proof of stake). This mechanism involves adding a new block to a user who has a certain number of coins. The more coins a user has, the more likely he/she will generate a new block.

Each subsequent block stores information about the previous one. Another important feature of blockchain is its decentralization, since information is simultaneously stored by all participants of the system (miners, master nodes). Thus, after the block is added to blockchain, it can not be changed or deleted.

2. How are blockchain transactions organized?

As it was mentioned above, transactions that are carried out in the network of blockchain do not require the participation of a third party. Let’s see how this happens in practice.

Let’s say you want to transfer 0.5 BTC to another person. Before the system recalculates the wallets’ balances (not transfer, namely, the recalculation), this transaction will fall into the so-called Memory Pool – the operational memory of all the miners connected to the network. After this, the blockchain transaction must be confirmed by at least 6 different miners. They (miners) should check the correctness of the transaction:

  • the amount of commission for each byte of information;
  • the physical possibility of adding a transaction to an existing block (if there is too little space left in the block, the transaction is transferred to the next one that still needs to be found).

After these actions, the data on the operation are permanently entered in the blockchain, and the coins are credited to the wallet of the recipient.

3. What features do blockchain transactions have?

Based on the abovementioned information, it is worth highlighting a number of features that are typical for blockchain transactions:

  • Irreversibility. Since the blockchain system is a decentralized system, it is not possible to affect the data that has already been entered in the register. Therefore, it is impossible to mark the already completed operation.
  • Lack of regulation. Due to the absence of the center from which the system is managed, it is impossible to completely prohibit and shut down cryptocurrencies. To do this, you must destroy all the computers of miners.
  • Anonymity. Each blockchain has its own level of anonymity, but in any case, even in pseudonymous anonymous networks, such as Bitcoin, for example, the names and surnames of users are never used for transactions.
  • Reliability. The network algorithm fixes the balance of all the wallets at the same time, but only a user who has a private key can make a transaction from a particular wallet. Subject to observance of elementary security rules, it is not possible to crack the wallet. You can lose your coins only because of your own fault. For example, if you send them to the wrong wallet, infect your computer or smartphone with a virus or somehow let scammers get private keys.

4. How to test a blockchain transaction?

Transactions in the Bitcoin network can be tracked on the site www.blockchain.info. In order to see information about a particular transaction, you need to go to this site and enter a unique transaction hash in the search bar. Then the system displays the actual information.

In this service you can also see information about a particular wallet:

  • transactions in the history (by dates);
  • the total number of coins that passed through the wallet;
  • the list of all addresses which there have ever been interactions with (incoming or outgoing operations);
  • current balance.

5. The reasons why transactions can freeze

The main problem of Bitcoin and many other coins is the speed of blockchain transactions. As for  BTC, this indicator reaches a mark of 7 operations per second. Previously, when the total number of users was small, this was enough. But now, with the growing popularity of the industry, the “line” for the transaction can turn into tens and even hundreds of thousands of unconfirmed operations. You can view the current list, which is updated in real time, on this service.

Some transactions may even freeze in the Memory Pool for a long period of time (up to 72 hours). What factors affect the speed of transaction confirmation?

  • Total pool load.
  • A very small commission. Miners confirm transactions with a larger commission in the first place.
  • The transaction weight is too big, and it simply does not fit into the almost completely filled block. In this case, it will be automatically transferred to the next one.

6. Conclusion

Cryptocurrencies have made a real revolution in the financial sector, on a scale that we still can not comprehend. The number of blockchain transactions is growing every year. In order for everyone to be able to use Bitcoin at the same time (like Visa, for example), it is necessary to solve the problem with bandwidth.

Blockchain transactions have both their advantages: the absence of intermediaries, small commissions, anonymity, security, and their shortcomings: irreversibility, low throughput.

Buterin, Winklevoss and Others: The Future of the Digital Currency World According to Major Crypto Personalities 1212

experts opinions on crypto

The crypto world has entered the new stage of its development, it has always been volatile, but these couple of weeks have been absolutely crazy: coins are jumping up and down, Bitcoin ETF is on its way, blockchain is taking over the world.

No doubt, crypto specialists and financial experts have a lot to say. Today we came up with a compilation of sayings from the stars of the cryptocurrency universe that we found particularly interesting and important.

The CEO of the crypto exchange Gemini, Tyler Winklevoss believes that the acceptance of cryptocurrency in the world as a means of payment equal to fiat will not happen in the next couple of years:

The vast majority of Wall Street firms are still not participating in the cryptocurrency market, which remains primarily a retail-driven market. This will change over time, but it will take time.

Pantera Capital’s CEO is way more optimistic on this issue. He sees great potential in the blockchain technology, and digital coins, according to him, are “superior form of currency.

Ethereum’s founder Vitalik Buterin wants cryptocurrencies to become more user-friendly and common in the everyday life. He also thinks it may become possible only in case the proper regulatory framework for crypto is developed by the state governments.

I want to be able to walk into a convenience store, get a card and pay a small fee to start using Bitcoin Cash,” he said.

The last, but certainly not least, is the CEO of BitMEX, Arthur Hayes, who has some serious doubts concerning Ethereum. According to his calculations, the price of the world’s #2 coin will drop lower than $100.

It is this moment,” he added, “that Ether goes from a 3-digit to a 2-digit shitcoin.

Although we are sure that experts know what they are talking about, the crypto world is way too unpredictable. We can only wait and see whether the abovementioned predictions turn out to be true or not.

Andreas Antonopoulos Criticized Bitcoin ETF 732

opinion on bitcoin etf

The well-known author of books about Bitcoin and the founder of his own Bitcoin-business Andreas Antonopoulos published a Youtube video where he expressed his opinion about Bitcoin ETF and explained why they cause so much sensation.

I’m going to burst your bubble. I know a lot of people really want to see an ETF happen because ‘too the moon’ and ‘lambos’ and all that. I think it’s a terrible idea. I still think it’s going to happen… I’m actually against ETFs,” he said.

Antonopoulos explained that he understands why many people are so impressed by the idea of Bitcoin ETF:

Everybody’s so excited about ETFs because what we’ve seen in other markets is that when an ETF becomes available—as we saw in gold—the price really increases dramatically as suddenly that commodity becomes available to a lot more investors and these investors pile on. But the other side of it is that there’s always these claims that the commodities markets are heavily manipulated and opening up these exchange-traded instruments only increases the ability of institutional investors to manipulate—especially [in the case of] large market makers—the prices of commodities, not just in the markets where it’s traded as an ETF but more broadly,” he clarified.


We remind you that the SEC postponed the decision upon Bitcoin ETF until September.

Marvel Is Not Happy About the Cryptocurrency Startup Using the Name Mentioned in One of Its Movies 637

marvel's trademark was used by crypto startup

Numerous startups try to create the hype using the names of famous people, companies, movies etc. The project Wacoinda was no exception. Its name is particularly similar to the word Wakanda which is a made-up African country in the Marvel movie “Black Panther”.

Wacoinda is a crypto startup aimed at providing financial education for African-Americans. By the way, this is not the first time a project used the concept of “Black Panther”. The famous rapper Akon launched his own digital coin and had plans of creating a crypto city in Africa similar to Wakanda.

Nevertheless, the representatives of Marvel did not quite support the endeavour of Wacoinda. They filed a lawsuit to the US Patent and Trademark Office asking to give them more time to decide whether they want to sue Wacoinda or not. The decision will be taken on the 14th of November.

A Review of the Odyssey Project or How to Transfer the Sharing Economy into Blockchain? 925

According to many experts, in the next couple of decades humanity will switch to the economy of general use (or sharing). This will concern many things that are accepted today (car, real estate, etc.). Within the framework of this article, we will tell you how this, not yet implemented common-use economy can be transferred to the blockchain. So, the review of the Odyssey cryptocurrency.

  4. Conclusion

1. What is the Odyssey cryptocurrency?

The main mission of the project is to combat the centralized sharing economy. In the near future, as the developers themselves assure, joint use will be quite ordinary, and personal possession, on the contrary, will become an unacceptable luxury. That is, within the framework of this economic model, You will not personally have anything, but You will be able to use what you want. Such an approach should lead mankind away from the consumer society and substantially raise the overall level of well-being.

This project comes from Singapore; its main idea is the creation of a decentralized version of the economy of the future, which will be oriented towards the common use of various things. The developers want to significantly reduce costs and increase the efficiency of marketplace applications, as well as create their own Odyssey system.

The main consultant of the project is the general director of TRON Justin Sun. Major Odyssey investors are:

  • Eddie Wu, Alibaba’s co-founder;
  • investment trust Vision Plus Capital;
  • TRON Foundation, etc.

The main principles of Odyssey:

  • everything can be combined and shared;
  • everyone has the right to possess information;
  • all participants in the system can count on income, which will depend on their initial contribution;
  • there should not be a monopoly in the sharing economy;
  • the new economic model will be effective only if it becomes autonomous.

Summarizing, we can say that the Odyssey system is a kind of marketplace for sharing, based on blockchain technology.

2. Odyssey in figures

This coin appeared relatively recently, only in early 2018. If you look at the chart, you can see that Odyssey’s currency exchange rate has significantly decreased from $0.09 to today’s $0.003.

The total issue is 10 billion tokens, now 4.75 billion are issued. Market capitalization as of mid-August 2018 is slightly more than $17 million. The coin takes the 244th place in the global rating of CoinMarketCap.

3. Forecasts

The Odyssey (ocn) cryptocurrency is now showing a negative yield, it is, to a large extent, related to the general trend in the market. It is rather difficult to predict the price of cryptocurrency in such conditions. Nevertheless, this project is potentially promising for the following reasons:

  • developers follow the schedule written in the project road map;
  • in the future, it is planned to create its own stock exchange;
  • the team actively works on the project, periodically consults the community through polls, voting, etc .;
  • the Odyssey project is closely connected with TRON, which ranks 12th in the rating of all cryptocoins;
  • economy of common use is the vector where the movement of mankind has already begun.

4. Conclusion

If you plan to invest in Odyssey, you should count on a long time, because the project is still too young and for its development there is still a lot to do. The sharing economy is also not tomorrow and not even in a year will become the norm, so that the global Xs in the near future should not be waited for. Also do not forget about diversification of your investment portfolio, this will significantly reduce the risks of a complete loss of capital. The Coin Shark continues to monitor the news of the cryptocurrencies and look for new promising projects.
