Every topic in a forum, the rivalry of these two cryptos are always being mentioned, amd thats why i always answer and reply the same answer and same opinion that i have, for me the bitcoin is the most consistent cryptocurrency that ever existed and nothing will change to that, but if only bitcoin will be bankrupt, but it is very impossible because the owner of bitcoin is very smart and wise. And the altcoin ethereum is not like that but bery useful. So i always conclude in every year bitcoin is very useful and effective.
