It is absolutely amazing the ways the Solana platform has really transformed in recent times, Kudos to its entire team. Now, many of us may remember that the coinmarketcap ranking is not a fixed position, it can change basically because different networks has different approach towards marketing, promotions; creating awareness and most importantly, consistent upgrades to it features frequently.
Etheruem which has been on the second position on coinmarketcap ranking for many years has been overtaken by XRP some years ago, and its also possible that other projects coins/token even Solana (Sol) can overtake Etheruem in near future.
I think that Solana has the potential to hit the number position, any day.
