tell me if it's a stupid question
ETH will not be able to replace bitcoin and become the king of crypto, but if you ask about the market capitalization, ETH can surpass bitcoin in the future, I think it can. The cryptocurrency market is always full of surprises. And in the past, ETH overtook BTC in terms of market capitalization but that didn't last.
You should stick or go to where you are happy and there is no need to follow what others are doing. If the good performance of ETH continues then it might steal the spot of BTC. This can be a big deal to some but if BTC supporters don't want this to happen then they need to support BTC harder than usual.
