Altcoins belong to different projects and serve different purposes. Some projects have only one altcoin, while others may have several. In this case, each of them has its own role in the ecosystem of the project. Before the advent of Ethereum, every altcoin appeared as a fork of Bitcoin or launched its own blockchain. However, Ethereum has created various cryptocurrency models, which has made it easier to launch new altcoins news blockchain technologies Instead of developing coins and new networks from scratch or a fork of Bitcoin, there is an easy way to create new cryptocurrencies. This has led to a significant increase in the number of new projects and the number of tokens on the market. As a result, an entire altcoin market has been formed.
