I don't think ETH will ever surpass bitcoin, It might reach a close market cap but it's going to remain under which Bitcoin has.
It will never happen. Eth cannot surpass and overtake bitcoin. It's just that there are too many ETH holders thinking that they can see one day seeing it at top one.
The fee of it is even higher than BTC which was the opposite before. Waiting for the next upgrades that they'll deploy to its network unlike bitcoin, it's been calm and lesser fee these days.
You couldnt tell because everything would really be unpredictable and there's no way that we could really make out some conclusions on how this market do ends up because ETH is just ranked 2 and we've seen that
dominance back in the past is almost really close to each other which people on time had already presumed that probability but well its too early to say but we cant really remove that kind of possibility.
Everything matters with the demand in the end because lots of people do believe that bitcoin would be number 1 in more years to come.
