Altcoins can be profitable, but they come with higher risk compared to established cryptocurrencies. Research thoroughly before investing. This is not a financial advice.
Many people have got high returns by investing in alt coins, so many people still invest in alt coins. Altcoins are cheap so many people take the biggest risk of altcoin investment in hopes of high returns. The price of Bitcoin has gone up a lot in the current market, along with the price of various alt coins. Failing to choose the right alt coin to invest in can make the money worthless. I think it's wisest to definitely invest in top coins rather than random alt coins. Although I get lower returns from Ethereum, BNB coins, hopefully investing in these coins is less risky than other alt coins.
