I did invest in lots of altcoins and i received many tokens from bounties as reward. I experienced that, most of the tokens turns into shitcoin or dead after a few months. Some Altcoins performed very good for a certain time then all of those lost 90-95% of values and still traded on exchange with so called volume. Thus process is continued. Even top altcoins also replaced by new altcoins. 2017 vs 2023.
Moral: I think BTC and ETHEREUM is better option for investment, Can be trusted blindly, profitable for long. Low Ranked Altcoins, Memecoins and shitcoins are just headache and reason of huge losses in long time. But anyone can invest his money wherever they want.
Your very right, investing in altcoin is a very risky practice that's why I just neglect it, most persons that are attracted to alcoins are there cause of greed and want to cash out those 50x or 20x on their investment but fail to understand that most of this project have no real world utility, and are mostly ran by centralized communities that have other agenda to dump the projects.
I won't write off all the other altcoin, but I think exchange coins are another good set of projects to invest inm even if they might be slow in growing but they have better chance of survival than most other projects in the crypto market.
Investing In bitcoin and Ethereum is good but I prefer to invest only in Bitcoin cause all other altcoin are just duplicate of that same idea and bitcoin is still very early and can still grow even more, so I'll rather use this opportunity to boost my portfolio before it gets really too late.
