I think BTC and ETH are the two best coin present. If bitcoin is 1, ethereum is 2. These are coin with solid base. They are trusted and used by investors.
you're right, the two coins are equally favored by investors.
both are very promising for long-term investments like one coin with two different sides but they remain side by side. the two coins are highly trusted by investors to get more profits.
if you invest in ethereum and bitcoin, you are very lucky in the future.
