BITCOIN VS DOGECOIN Bitcoin What is Bitcoin Bitcoin is digital money. Physically, this currency does not exist, there are only special registries that keep records of how many bitcoins someone has and who transfers them where. These journals are called blockchains. This is similar to how non-cash payments are arranged in banks: when you pay with a card in a store, you also do not transfer any physical money or gold to anyone. It's just that your operation is registered somewhere in the bank register. Bitcoins differ from regular currency in that registries are not stored centrally in banks and payment systems, but simultaneously on all computers that are occupied by bitcoins. Anyone can watch all transactions with all bitcoins in history. Registries are protected by cryptography. You cannot fake them all at the same time. There is no way to rewrite data in blocks and claim that someone now has millions. Bitcoin is pretty secure in this sense. True, there is already an attack that allows you to pay twice with the same bitcoins, so it is impossible to say that bitcoin is absolutely safe. Where do bitcoins come from Common currency is issued by the state. It is very indirectly connected with gold reserves, but in fact it is not connected with anything - as much as the state needs, it will print as much. Bitcoins are not associated with any one state. New units of bitcoin emerge as computers on this payment network serve the needs of this same network. For example, somewhere in China, a person paid with bitcoins for a pizza. This operation must be recorded in the registries on all computers that are connected to the bitcoin network. To record an operation in the register, you need to seal it with a special signature, like a wax seal. This signature needs to be calculated, it is a complex computer problem. Somewhere in Venezuela, there is a computer that powers the bitcoin network. He just figured out this cryptographic signature. As a token of gratitude, the owner of this computer receives a reward in the form of a bitcoin penny. For a Venezuelan who has set his computer in the mode of calculating cryptographic signatures, it looks like this: his computer is rustling something, and bitcoin-kopecks are dripping into his account. The computer seems to be mining bitcoins, although in reality it simply encrypts and seals other people's transactions. This kind of "extraction" of bitcoins is called mining. In fact, it is not the bitcoins themselves that are mined, but the "sealing wax" to protect the registries. Bitcoins are a reward for service. The number of bitcoins is limited - there can be a maximum of 21,000,000. In the summer of 2020, miners mined about 90% of the coins. Mining is a separate big topic. In a nutshell: the equipment is expensive, the efficiency is low, you will have to compete with the megawatt Chinese mining clusters that are built on the basis of power plants. Why bitcoin is needed Cryptocurrency allows you to transfer money under a pseudonym and without the participation of banks. 1425 RUB the average cost of transferring bitcoins at the beginning of April 2021, according to bitinfocharts.com For bitcoins, you can buy an Airbaltic ticket, a Dell computer. You can even donate bitcoins to a Buddhist temple in Seoul. Bitcoins are traded on the stock exchange, money is invested in them. Since 2015, bitcoin has risen in price from $ 200-300 to $ 60,000 and continues to grow. This made cryptocurrencies interesting for investment and speculation. Interest is fueled by success stories. In 2009, Norwegian student Christopher Koch randomly bought $ 24 worth of bitcoins. He remembered the investment after 4 years, when his fortune reached $ 885,000. And I bought an apartment in Oslo with a part of the money invested. What is DogeCoin cryptocurrency? However, such blockchain companies, most often, cannot bring super-profits to their investors, since their assets are already quite expensive. Therefore, it is not worth considering them as a highly profitable instrument for investing your funds. At the same time, there are lesser-known projects with a relatively small capitalization on the market, which large investors prefer to avoid. However, together with a small amount of capitalization, such cryptocurrencies often have an interesting idea and serious growth prospects. One such project is Doge with its personal currency DogeCoin (DOGE), which no one has taken seriously before. It is believed that this digital asset is a parody of a real cryptocurrency, which was created just for a joke. There is a legend that Doge was invented on the 4chan image board and was actively promoted by its users. However, during a growing market in late 2017 - early 2018, when all digital assets reached their peak, DogeCoin was able to grow in capitalization to almost $ 2 billion, and its price rose from $ 0.0002 to $ 0.016.
