True, ethereum is a very dynamic coin because it can be used for multi projects, even if in total all tokens and ethereum it already controls more than 65% marketcap and bitcoin is only about 18% marketcap, this is what makes me believe that one day ethereum will replace bitcoin in the first position.
Well, the truth is, I do not think that ETH will replace BTC, ETH is very good, it has its own network for carrying out projects and has a considerable currency value, however it is necessary to highlight that it has many cons, in the network eth its fees They are exaggeratedly expensive, these days I changed a couple of currencies that they paid me on the ETH network and they charged me more than 150USD in pure commissions, for many it is nothing, but for me that is too much, also if we take into account that each time that BTC falls in price ETH suffers very radical falls, and BTC has a life of its own, while ETH does not, those are the reasons why ETH can never replace BTC.
