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.
If Bitcoin reaches $ 100,000, Dogecoin will forever never reach $ 1 because Dogecoin's supply is huge and its development team has not been active much lately. I think dogecoin needs a new revolution because if the team does not develop then this is the shitcoin of the Cryptocurrency market.
