Well they are working hard to do so, envy the ones that has come up with a solution to those problem has not been able to completely implement the solution, I though Binance after creating their own chain would have built on this problem of ethereum for them to outshine eth, buy yet, ethereum is still growing stronger than majority of them that has believed they are better than ETH.

For some days now, ethereum has been getting lots of investors who believe in their projects, even with all the problems they are yet to solve which I still believe that they are still the best in their field for now, I know as time goes on, all these problems will fade away and give ethereum more strength to continue rising above other competitors.
