Ethereum has a big name and is so well known that's almost impossible to defeat unless they make a huge mistake.
I don't think one needs to wait for their competitors to make some mistake in order to move up in the market. Competition is good for the sake of innovation.
competition is really good, it helps innovation, it decreases prices, costs, ethereum has a good and functional blockchain, maybe dusk should focus on the characteristics that ethereum does not have, for example, anonymity to be a valid alternative...
