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.
Bitcoin is Bitcoin you can't compeer anything with bitcoin and Ethereum is a top altcoin also also a strong chain Ethereum (ERC20) provide a high quality contract address with high security that's why this blockchain is much popular. so i think ETH is also safe investment in altcoin. you can also choice another top altcoin for investment like SOL, BNB and any others coins like this. but always invest such a amount that you are afford to loss. because no cryptocurrency coin will not give you any profit guarantee
