$BTC
Bitcoin has enabled the development of many pioneering sectors and technologies in the cryptocurrency world, both because it is a pioneer in the cryptocurrency world and because its technology is limited. In addition to the technological revolution that Bitcoin brings, the fact that the Bitcoin blockchain structure is transparent and has a limited supply has caused it to be seen as an investment with low inflation and high potential for many investors.
Since Bitcoin could not provide sufficient capacity in terms of both speed and scalability after its birth, it has also given birth to many different cryptocurrencies. These cryptocurrencies are called "alternative coins", in other words "altcoins". These cryptocurrencies, which are developed in a similar or different structure to the Bitcoin blockchain, can be programmable and have a faster structure.
While alternative cryptocurrencies were being created, competitive advantage was used at various points by having different features and new cryptocurrency types emerged. The main differences between these cryptocurrencies are the maximum supply that can be produced, the algorithms used, and the types of blockchains (private/shared, permissioned/permissionless consensus).
