Thinking of the future bitcoin will stay become the number one as bitcoin was has more fan then ethereum. Like or not bitcoin still like a father for all altcoins so i dont think peoples will dump bitcoin for Ethereum. But i still do think ethereum will be stay at number 2 and hope xrp shit token will not replace ethereum at second anymore.
Yeah bitcoin definitely has its own fanbase that's not gonna switch to any altcoins other than just for making profit and Ethereum too has fanbase all over the world. but, Ethereum's growing pace both in market cap and development of projects within the platform is kinda fast that it's not impossible for it to eventually overpower bitcoin in the future but whether it's gonna happen or not it's always good to have some kind of competition.
The exchanges out there also keep contributing to build up the ETH hype, kinda curious when the future unfolds and we gotta see which coin dominates.
