Technologically, I do see that ethereum is better than bitcoin. Technologically, ethereum is an almost perfect technology. Ethereum has almost no defects at all. But this great technology brought by ethereum is inferior to the popularity and trust that is too ingrained in bitcoin. Bitcoin as the first crypto currency coin is very pervasive in the hearts of the people so that bitcoin is still the king of crypto currencies. I am sure that someday ethereum can replace the position of bitcoin as the king of crypto currencies. This is because the technology carried by ethereum can last a long time and still provide real benefits. The longer the society will risk more profits than just mere popularity. So if you want very large profits then you can invest in ethereum from now on. That is a bit of my thinking. I love ethereum very much. Ethereum is a potential coin for the future. I believe that.
