It is true that right now we are hard to believe in altcoins since most of them have not really good performance. But trust me that two altcoins (ETH and XRP) are always good to invest. These coins commonly follow the trends in Bitcoin. So, if this year or in 2021, the Bitcoin will have a great season, I am pretty sure that ETH & XRP will probably have a good season as well.
I think the success of these two coins is absolutely independent of each other.It will all depend on what kind of benefit they can bring to people in the end.
