Just wondering if ETH can
maybe it can, because we can't guess everything. the problem is that eth is always improving, and we also don't know how the next development will be. if eth wants to compete with btc it also has to do hard work. because btc has also reached quite high.
before answering such questions, we must compare not only the capabilities of Bitcoin and ethereum, but also putting them at their level to make an analysis of their functionality and relevance for today. I believe that ethereum economically and in terms of use is much more in demand.
