For me the answer is obvious. Bitcoin is a more reliable value. This is happening even now. In the long run it will be even more pronounced. The mechanism of inflation underlying the Ethereum will never allow him to become promising in the long term. He's probably already reached my limit.
I agree with you.
I am very difficult if asked about my opinion about something in the future, because we never know what will happen later. But according to my predictions that are more profitable 5 years later is bitcoin, because the price is very good and will be difficult rivaled by other coins, although ethereum will have a good price, but I think it will not be as good as bitcoin. , it would be better if we invest in both, so the money we get will be more and more, because both will have a higher price.
