it is not reasonable for us to comparison between Bitcoin and dogecoin, bitcoin have a good fundamental, and doge just "meme" coin.
and you must be choice Bitcoin.
Without answering of course most people already know if they have to choose, but for me as long as DOGE is still profitable then investing DOGE is a better thing than bitcoin, I make cryptocurrencies as daily trading and opportunities for daily profit are easier to get with DOGE.
