However, altcoin investment isn't bad because it has made many millionaires in the cryptocurrency market. But where it becomes bad is when the newbies doesn't understand the risk behind it. But for he that understands the risk and abide by it, there's nothing wrong with altcoin investment.
Indeed, investing in altcoins is not all bad. I am also investing in them and believe that most people also invest in altcoins because nobody doesn't want a lot of money. But as a newbie, inexperienced, you should stay away from altcoins and only invest in them when you are knowledgeable and aware of the risks that it brings. We can't deny that altcoins are giving better returns than bitcoin these days, but to find altcoins that do, not everyone can. Investing in altcoins is interesting, but it's not for everyone.
