You can say ethereum chain is a bit faster than bitcoin but not that ethereum too is that best in the market to overtake bitcoin. There has been nothing new about ethereum and all the upgrade they have done so far still did not solve their own problem too or make them gain recognition more than bitcoin.
So why do you think it is now that there are so many people even competing with Ethereum, while it is possible for BNB and EOS to overthrown ethereum. My friend, it is not bitcoin you should fear for, it is really ethereum that you should fear for, because speed or no peed, bitcoin will always remain dominant while we already have some projects that could send ethereum packing.
