Just follow Ilon Musk twitter or his social media as he is a dogecoin lover. He had tweeted about them few weeks ago and dogecoin price went up for 25%. Plus on January 2 the price was pumped thanks to Bitcoins price growth. Dogecoin price is super hight right now. Wait a bit for its drop, buy and wait till Musk mentioned dogecoin once again, and sell. That should be the best tactics.
