I can only say one thing, Bitcoin (BTC), Ethereum (ETH), Binance coin (BNB) will remain the leaders of cryptocurrencies. They are stable, reliable, the risk is very low and profitable, but bitcoin is generally the market leader, so this is the best option of all.
Which is an easy and safe way to navigate the market, but humans have the nature of taking risk because its "tasty" for them to and therefore they will go with more risky options, which include gambling with their money, going with the less known pumping and dumping altcoins. Eventually they will get burnt and then become disciplined to focus on the top few coins.
This comes with experience and the questions pertaining to them also are symbols that the OP might be naive but willing to learn. A safer method to play with the risky altcoins is to do it all on paper and see for yourself how much they are easy to lose money in.
