Ethereum still has to work very hard if ETH wants to beat Bitcoin because I see the price difference is very far from Bitcoin so I think in 2020 bitcoin is still the market leader.
bitcoin will remain very strong if there is no official rule that eventually binds ethereum as the main conversion of crypto economy, I think ethereum has the power to beat bitcoin anytime, but they are still silent and waiting for momentum, a very reasonable reason because if eth is on the top of the market volume then CEO and their developers will always be busy with various cases of public indictments that will hamper system development.
