Dogecoin is a meme coin - be cautious about it. It follows the overall market quite well, but if you buy some in a wrong moment, you might be stuck on the loss for a while. If that happens, typically if you wait long enough, you will get your money back. Better investment: Eth (during the next dip), Polkadot (now) or Stellar/XLM (wait for a dip) and in the future, Filecoin and DFinity. Good luck!
