I have never even heard people say $ 1 for Doge, don't expect that price because the total supply of Doge is very much and it is impossible to reach that number, I also advise you to be careful because the increase in doge price is only FOMO and can fall quickly
Dogecoin is a shitcoin, don’t do it. Dogecoin already in trading overvalued, so don’t follow the FOMO. Rather wasting money at doge better look into more solid projects like small market cap coins. Don’t think too much, otherwise you will lost most of it.
