Let me show you some NBA perspective on this, bitcoin is the king of cryptocurrency right? same as LeBron as the king of NBA. But here comes ethereum the prince of cryptocurrency just like Ben Simmons as the prince of the NBA. The prince will dethrone the king on the eastern conference finals same as ethereum that will dethrone bitcoin in the next couple of years. Wether we like it or not the king will reach its limit. Mark my word. Trust the ethereum process!
I do not know why people always say that ethereum threats bitcoin, or bitcoin compared to ethereum.
They are cryptocurrency different and there is no reason to compare both.
They are created with different goals and concepts, you are wrong.
