It is possible to reach. Nobody ever thought in 2009 that BTC will be 1300 usd
Impossible to reach, if the price is one USD, it means the total market cap will be 108 billion USD, bitcoin only has 20 billion USD, how can dogecoin be that large market cap? 0.001 usd is more realistic target for dogecoin. It is still 5X based on current price. Dogecoin keeps out of top 10 for one year, without cutting-edge technology, the price won't be higher any more.
I didn't said that it's realistic or it will ever happen. Doge was/is just a clone which dosen't really brings anything new to crypto.
