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.
I've had similar experiences with altcoins. Many I've invested in turned out to be "shitcoins" or lost value over time, with Ethereum being the most successful one I've held. As a result, I rarely hold altcoins for a long period, typically no more than 20% of my portfolio and for a maximum of one year, sometimes selling them within hours of their market launch.
