Maybe some people speculated that ethereum will replace bitcoin but for me, I think that's far from happening. Bitcoin's value is too far from ethereum's. Bitcoin has been dominating the crypto world for so long already and replacing it from the top would be a very difficult job. Bitcoin might go down a bit this year since its value suddenly pumped up so high last year but I don't think it would reach to the point where it would go near ethereum's value. Bitcoin never stops surprising us so let us put our hopes high on it always.
