Ethereum is a threat to bitcoin? Yes it is. We all know that ethereum was created by a russian programmer on 2013, and it was launched on 2015. After 3 years it is next to bitcoin in terms of popularity and value.
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 don't see it that ethereum is a threat to bitcoin, it's not a competition and not comparable.
Bitcoin is the most powerful and popular in the crypto world because of he's potential and the huge value than ethereum. King is always be the king.
