As you already said, altcoins can scam, death, tuun into shitcoin and so on. I agreed that most of altcoins fail to survive for long term But not all atcoins are bad! If you have high expectations, and buy shitcoin for more roi, then thats Your falut. If you invest valid potential altcoins, then theres very less possibility that those Will be scam, dead or shitcoin. Low your expectations and invest with potential coin. If you Don't know how to find out then you can invest with top 20 crypto-currencies. Although you need to notice that, avoid memecoin, and shitcoin like tron. Otherwise all seems okey
Well, I do agree with your point that someone who becomes greedy for more profits and invests in meme coins or coins that are just launched and don't even have any potential or actual use case tends to lose more money because such coins and tokens are never guaranteed to provide their investors with profits. We've seen a lot of projects getting millions of dollars in investments but at the end of the day, they failed to provide anything to their investors.
So the best way is to simply choose altcoins that are trusted and have been around for quite some time just like Ethereum, Litecoin, Monero, and many others that we know have got the potential to perform well when we enter the bull run and we can get good profits if not huge from these investments.
