The coin supply of doge is too huge. For doge to reach $1, there must be some major adoption of doge worldwide and many users are buying doge. Perhaps it will happen when BTC is worth few hundred thousands.
I do not even understand why people are so naive and try to explain why one should expect great prospects from the dog. Well, if there is no good demand for a coin, then no one will buy it. This is the law of the market.
