As long as bitcoin continues its high dominance, nothing can beat bitcoin, it will remain in the top. Bitcoin has an anonymous creator, and that's the purpose of bitcoin which is to bring anonymity and the brand of our market is bitcoin, without bitcoin crypto would not be popular.
Bitcoin will not give anonymity, the creator is anonymous but that is a completely different story altogether and it started the market but what does it do in the context for other coins. BNB rallied and you should thank ETH for that as the delay in transaction has forced some developers to move to BSC and that helped them gain momentum.
Some thing has to give for another to take. The demand for a service cannot wait for no one, in every day life, if a supplier fails to supply, then attention is given to another supplier. I guess the Binance chain team should actually thank the Ethereum network for their short fail with regards to this high gas fee which lead to this movement and also, Binance have their own issue too cos i have seen traders complain about their Futures market hanging when there is huge market upside movement leading to monies lost which could also affect that side of the exchange. Some ones lost will always be someones gain.
