I will start taking this talk of Ethereum flipping Bitcoin serious when Ethereum is done with its scaling issue, Ethereum have this issue now that it could become useless for Dapps and if we can get a successful L1 scaling solution on other platform this could be the beginning of the end for Ethereum. I just hope the fee and the transaction speed is brought down significantly
That is what they are working on as of right now as well. They are moving to ETH 2.0, and in fact they already achieved phase 0 of it as well, so now they are just letting it work and they are developing for phase 1 and when phase 2 comes we are going to have full scale eth 2.0 . At that moment we are not going to have any fee at all charged for miners because there won't be miners, it will be people who stake and the more people stake the faster you will pass, by logic if there are little amount of transactions it is going to be literally free, but with a ton of transactions right now, it is going to be at least cheaper.
However what I assume will happen will be since 2.0 will be something awesome, the price of eth will be higher, and there will be a lot more transactions, so it would be profitable but also it will cost even more than right now because of all the demand.
