The current valuation is crazy and time will tell for a project that has nothing in production currently. The space is still open for some of these Ethereum competitors to take the top spot form Ethereum before the launch of the Ethereum 2.0 and if some of these new projects fail to come up with a solution to the scaling solution than bye-bye. I still feel the project is over valued at $4 billion Mcap
I just went to coinmarketcap, BNB is still in the top 10 and no change has occurred. Looks like you checked it out at coingecko? Btw Polkadot is a big project and I believe it will rapidly grow strongly in the future, and the top 10 altcoins in 2021 will have this project name.
Polkadot is only seen on coingecko and thats where BNB is displaced in top 10, whereas Polkadot is does not apear to list above BNB on coinmarketcap. Polkadot almost got full dilution which could be the reason for the high marketcap and I think it could distracting information. If binance list DOT and also owns coinmarketcap with possibility of been bias, I dont understand the reason for the difference in chat position.
it is true that you said, polkadot can shift BNB only on the coingecko that is visible while the coinmarketcap is not true.
