I only know bitcoin and Ethereum. I want to know where you get the new coin information and how to judge it as a good coin.
As the number of alternate cryptocurrencies increases, and many of the newest coins offer an opportunity to increase one's investment. Almost all new coins worth mentioning are listed on the CoinMarketCap website. CoinGecko is another method for finding cryptocurrency coins. However, there are also many risks associated with these coins, since it's difficult to predict which coins will attract the most attention. When it comes to investing in cryptocurrencies, it's best to put at least 70% - 80% of your investment in established coins like Bitcoin and Ethereum.
While it might be tempting to buy altcoins because they are cheaper, or because they are perceived to be cheaper by the market, this isn't the best approach. Make sure that you have a balance between more established and more mature coins in your portfolio.
