Altcoins can be profitable, but they come with higher risk compared to established cryptocurrencies. Research thoroughly before investing. This is not a financial advice.
I think this topic has been discussed several times on this board. Everything can turn into a good investment if you can make a profit from it. A meme project can be a good investment? yes it can if you know how to make a profit out of it. Investing in bitcoin can be a bad investment? yes it can as well if you don't know how to manage your risk. Its not about altcoin or bitcoin being a bad or good investment. Its about how you can manage your investment and what its outcome will be.
