There are more than seven thousand altcoins in the world, and many exist in an inert state or have a small capitalization, that is, they do not affect the market uncluding nerpay.
Bitcoin is the first cryptocurrency and still holds the largest market share. A couple of years ago, it was the main asset for investing in cryptocurrency.
Now ether can compete with it. Often people invest in it not only as a coin, but also as a technology. Most decentralized finance applications run on the Ethereum blockchain.
In addition, new cryptocurrencies are taking off in the market. As of October 2021, Cardano (ADA) is the fourth coin by capitalization. She showed a sharp increase in August this year, although few people heard about her a couple of years ago.
