I think Dogecoin helps it, its a friendly way to get people into crypto, the community is nice, the coin is fun.
I don't know why people think its Dogecoin vs Bitcoin.
bitcoin has much big community and adoption than compare with doge, so in my opinion bitcoin do not need any alt coin for its adoption.
True. Tbh, there isn't much of a competition between Dogecoin and bitcoin. Dogecoin is meant to be a not-so serious coin after all, whereas, bitcoin is designed to be the currency of the future because of its innovative technology. Imo, bitcoin can still see worldwide adoption even without the help of other altcoins. It's just a matter of good pr and any other good stuffs relating to/related to bitcoin.
