Many people like to play with altcoins, and I used to enjoy playing with them as well. I made money, I was crazy, and I also suffered losses. Now, I honestly focus mainly on mainstream cryptocurrencies like BTC, ETH, SOL, BNB, etc. How to put it, everyone has dreams of getting rich quickly, but for most people, those dreams will be shattered. It's important to stay grounded. That said, I can't say not to play with altcoins; small investments are fine, but for larger investments, it's better to stick with mainstream coins.
