impossible and will never happen because BTC is the first coin that controls the market and has the highest price so BTC will remain in number 1 forever
I can see another true believer of bitcoin right there, I am glad I belong to the community of bitcoin also and aside the fact that I am a bitcoin holder, I am also an ethereum holder but I know that come 20 years’ time, ethereum may not even be sitting on that position, probably they will be below top 10 and not to talk of really meeting up with bitcoin in function and services.
From the recently bull run of bitcoin, there even lies our answer because we can see that as bitcoin goes up, ethereum also goes up a little and as bitcoin goes down, ethereum does the same thing, ethereum has not really moved personally without BTC BULL, and that is a coin that wants to outperform BTC.
