In the fledgling field of digital currency, Bitcoin had little to no competition when it first debuted in 2009. However, by 2011, new types of cryptocurrencies began to emerge as rival platforms and currencies launched their own products using the blockchain technology on which Bitcoin is based. Suddenly, the rush to produce more cryptocurrency began. The rush to cryptocurrency is an explosion of financial services that has swept the globe and is not limited to just one nation. It would be an exaggeration to say that cryptocurrencies are now in widespread use. The cutting-edge nature of cryptocurrency blockchain technology is one of the reasons why it has captured the hearts, minds and wallets of so many people. It's amazing how widely applicable blockchain and the idea of decentralization are in our society, not just for the financial sector. There's also the incredible speed of blockchain technology, international money transfers that previously required a wire transfer could take just a few minutes on a quiet day. The causes of cryptocurrency success seem to last forever. Numerous characteristics of cryptocurrency appeal to both human imagination and practical requirements. This paper was made with the aim of identifying the impact of the value of Bitcoin on the value of selected cryptocurrencies. By analyzing numerous sources and data, it was established that there is a direct correlation between Bitcoin and selected cryptocurrencies. The use of such information helps in analyzing cryptocurrency prices and in understanding the cryptocurrency market itself and its price movements (cycles). Bitcoin is the most famous cryptocurrency and the cryptocurrency with the highest capitalization. Also, Bitcoin is a representative of the crypto market, and any influence of the media and social networks directed towards Bitcoin significantly affects the selected cryptocurrencies since they follow its market movements. It is important to emphasize that the selected cryptocurrencies are more volatile than Bitcoin itself. Bitcoin has the largest network, the most credibility in the eyes of institutional and retail investors, and is built on top of the most secure database ever. Bitcoin's unchanging monetary policy is what provides users with the greatest guarantee that it will not be replaced by another cryptocurrency. There is no way to improve this quality of technology. Tens of thousands of nodes around the world enforce Bitcoin's monetary policy by independently validating every transaction on the network. Bitcoin's monetary policy cannot be changed by a board meeting vote, unlike central bank monetary policy. "
