OP, you chose ethereum to invest in altcoins which is good. If someone wants to invest in altcoins then he should choose Ethereum as the 1st choice, because the most popular and trusted coin among altcoins is Ethereum. Investing in altcoins is very risky but investing in some altcoins can expect good profits. However, if I was asked to invest in altcoins then my 1st choice would be Ethereum followed by BNB SOL MATIC investing in these coins can expect good profits. I have invested in the coins mentioned above.
