It's apparent that BTC almost always comes first than any other altcoins, including Dogecoin, and if the altcoin has no investment potential, then there is nothing to compare in general.
I do understand if the comparison is done between bitcoin and ethereum or bitcoin and bitcin cash but I am really unable to find the reason behind this comparison. I mean neither dogecoin is number one altcoin nor it was made for killing bitcoin. Even the haters know that bitcoin is the best of the best in cryptocoin world and no other altcoin can surpass it in any sense.
