DOGE is a phenomenal coin is sense of its growth. It has enormous upside to it, including getting listed on Robinhood exchange this Q1-Q2 of 2018 which will just make the market go wild, especially since Doge is very cheap and although that plays no role in reality, it has a great effect of psychological state of people. We tend to think that the, "Cheaper this coin is, the bigger is the potential to get 'rich fast'." - that is not true, however you will not change how people think, only take advantage of it.
I wish you all luck, plus to give you guys a rumor... Coinbase is said to be adding several new cryptocurrencies to its platform, and one of those will most likely be DOGE Coin.
